+ make the Index Application space name simper for a better display in XWiki's UI
+ remove the space wording

## Issue

https://jira.xwiki.org/browse/XWIKI-8346

## Solution

  * Check two schemes when executing load backlinks request: with and
without the wiki id.
  * Ensure that the right wiki is used in the context in DefaultLinkRefactoring

## Limitation

This fix some issues related with updating link on farms, but such operation still require to set the property `updateLinksOnFarm` when doing a refactoring, for performance issue.

  * Since we removed the ConverterManager from AbstractMacro and it's
used in BeansManager we need to register a mock component for it in RSS
Macro test.

* Add new configuration option

This reverts commit 0e5ac713.
This has been properly fixed by XWIKI-16181.

  * Use explicitely the new type serializer

  * Use a more easy to read replacement path

  * Fix tests

  * Clean the path before returning it in getTemplate
  * Fix some tests

  * Extract method to compute link references in XWikiDocument
  * Add a toString method in XWikiLink
  * Add a new test for getting XWikiLinks in XWikiDocumentTest
  * Add a new test for toString method in XWikiLinkTest

* Update page object and functional tests

* Remove the form used by the class switcher as a no-JavaScript fall-back since it doesn't work anymore with the new class picker: the selected value is the class reference not the class URL. I don't think it's worth keeping two pickers, one that selects the class reference and one that selects the class URL. Another option is to add support to RedirectAction to redirect to a page specified in the URL, but I'm not sure it's worth implementing.
* Allow the users to cancel the class switch

* Use the classPicker Velocity macro on the class editor (to switch to a different class)

* Use the classPicker Velocity macro on the object editor (to select the type of object to add)

* Improve the suggestInput Velocity macro:
** Serialize non-string attribute values as JSON
** Add support for customizing how the option elements are generated, by passing the name of a Velocity macro to be called (optionsDisplayerMacroName)
* Add a classPicker Velocity macro similar to the userPicker and pagePicker macros
** Use the EntityReferenceTree to sort and group the classes by location (generate an option group for each location)

Small fixes / improvements to the selectize widget in order to be able to use it for the xclass picker:
* [Fix] The selected value overflows the dropdown caret on single selection (this is visible when the widget is inline-block and thus doesn't take the full width)
* Add support for left/right alignment of the dropdown menu when the dropdown is a child of the selectize control (e.g. the xclass switcher is aligned to the right)
* [Fix] The padding around dropdown items (suggestions) doesn't match the padding used on the other Bootstrap menus we have
* [Fix] Show the loading icon when typing only if remote loading of suggestions is used (e.g. the xclass picker doesn't use remote loading)
* We don't need to update the downdown possition if the dropdown is a child of the selectize widget
* Add a new configuration option 'takeInputWidth' to take the width of the select element when the page is loaded (for when the widget has inline-block display).
* Initialize the selectize widget for fields having the 'xwiki-selectize' CSS class (the alternative would have been to add a suggestClasses.js that only loads xwiki.selectize.js)

XWIKI-16187: Events are not displayed even when the "Read Event Filter" is off, if all events are read.

* block the redirects as they are leading to an unexpected result for the annotations UI

  * Fix potential NPE when using multilingual wiki with no locales set
in the request.
  * Add a new test for ensuring the case.

This reverts commit 2d74b203.

  * Catch the InvalidPathException when a path with unsupported
characters is created and returns null string.

XWIKI-16170: Renaming level 3 (and higher) pages moves them to a wrong (automatically created) parent page
* Fix AWM rename also.
