Fix auto-selection of URL field with X11 selection

We use `focusin` event instead of `click` because when using the latter,
when the selection is created it isn't put into X11 PRIMARY selection.
And as a Linux user I'm very used to such behaviour that when something
gets selected, it's ready for pasting, which is the primary purpose of
the clone URL field.

When `focusin` is used, the selection is copied to X11 buffer
automatically, so it works as expected (tested in Firefox and Chrome).

This reverts commit d365004e.

Having a merge request with a comments on a line which is then changed
in a later commit prevented new comments from properly showing up in the
merge request show page.

 * `Note#set_diff` do not use stored the diff when creating a new note
   in merge requests (we can not be sure the diff did not changed since
   the last comment on that line)
 * Do not rely just on `outdated?` of the first note when displaying
   comments of a MR in the discussion tab, but partition the
   active/outdated notes and display them all
 * In the inline changes tab just select the active notes, so an
   outdated note does not prevent an active one from being rendered
 * Just show active comments in the side-by-side changes tab

Make sure user has access to namespace in import tests.
