We added a dependency to dashboard-ui in an older commit in which leads
to having a template provided. As a consequence we cannot anymore just
rely on /create/ URLs and expect to obtain the editor: our logic is to ask the user for chosing the
template in such scenario. To avoid that, we can just provide an empty
template parameter to simulate that choice.

Improves the screenshot in case of error.

  HTML validation error

* update test to take into account the fact that indexing links is slightly slower than it used to be
