XWIKI-18003: Pencil buttons on profile page are not consistent with the used icon theme and missing contrast (#1671)

* Add pencil icon in profile edit link
* Update profile edit link style

* Use the plain user name as the alt attribute of the user profile
  picture
* Make sure that only one link to the user profile is added in each
  event

  * Use the context component manager

* Also make remote debugging work when using the Jetty container

- Resolve user page reference relatively to the wiki reference it
  belongs to, when controlling access

@vue/vue2-jest becomes a mandatory with vue-loader:15.10.0.

  * Fix properly tests by using wiki reference for the reset password
    URL

XWIKI-20012: Switching to / from Source mode while in WYSIWYG editor could include unexpected content

  * Add missing revapi ignores for changes related to reset password
  * Fix a test by using the proper action resource URL

This provides two things: the fix of the bug by handling a wiki part in
the URLs for authentication resource, and a rename of the authentication
resource action (forgot becomes retrieveusername and reset becomes
resetpassword).
Note that the latter changes are not backward compatible, but they were
still unstable (since 13.1RC1).

Fix an issue where the cell above the target one is opened in edit mode by accident.
