Pass user instance to Labels::FindOrCreateService or skip_authorization: true

It fixes a bug described in #23694 when `project.owner` was passed to `Labels::FindOrCreateService`. `Labels::FindOrCreateService` expected a user instance and `project.owner` may return a group as well. This MR makes sure that we either pass a user instance or `skip_authorization: true`.

Fixes #23694

Fix events order in users/:id/events endpoint

Order of events in contributions API is currently being lost, though docs are saying:

> Get the contribution events for the specified user, sorted **from newest to oldest**.

Order becomes different after `.merge(ProjectsFinder.new.execute(current_user))` call, so I moved ordering below this line.

This MR also removes extra `.page(params[:page])` call in the method chain, since [`paginate(events)` already does it](https://gitlab.com/airat/gitlab-ce/blob/master/lib/api/helpers.rb#L112).

Reduce overhead of LabelFinder by avoiding #presence call

Some users experienced 502 timeouts when viewing group labels.
Labels#open_issues_count and Label#open_merge_requests_count were

that only the IDs are loaded into memory.

Fix `User#to_reference`

Fix the method signature of `User#to_reference` so that moving an issue with a user reference does not throw a "invalid number of arguments" exception.

1. Changes in 8.13 require `Referable`s that don't have a project
   reference to accept two arguments - `from_project` and
   `target_project`.

2. `User#to_reference` was not changed to accept the
   `target_project` (even though it is not used). Moving an issue
   containing a user reference would throw a "invalid number of
   arguments" exception.

3. The regression was introduced in [c8b2b3f7](https://gitlab.com/gitlab-org/gitlab-ce/commit/c8b2b3f7c32db873f1bebce3e3b1847ea24d235f#91fabb7ad88bd2fde6fef1c100a719c00e503047_75_79), which expects
   all `Referable`s that don't respond to `:project` to have a `to_reference`
   method that takes two arguments.

Fix bug where labels would be assigned to issues that were moved

If you attempt to move an issue from one project to another and leave
labels blank, LabelsFinder would assign all labels in the new project
to that issue. The issue is that :title is passed along to the Finder,
but since it appears empty no filtering is done. As a result, all
labels in the group are returned. This fix handles that case.
