This index is added on `(target_project_id, iid)` and has a `WHERE state
= 'opened'` condition. Using this index we can drastically improve the
performance of the query used to count the total number of merge
requests in a group. Without this index the query would eventually
perform the following:

    ->  Index Scan using index_merge_requests_on_target_project_id_and_iid on merge_requests  (cost=0.43..4.89 rows=7 width=4) (actual time=0.058..0.353 rows=6 loops=228)
          Index Cond: (target_project_id = projects.id)
          Filter: ((state)::text = 'opened'::text)
          Rows Removed by Filter: 141
          Buffers: shared hit=34351 dirtied=1

Out of the ~180 milliseconds the entire query would take, around 170
milliseconds was spent in just this segment. With the index in place,
the above segment is turned into the following:

    ->  Index Only Scan using yorick_test on merge_requests  (cost=0.42..0.55 rows=7 width=4) (actual time=0.004..0.010 rows=6 loops=228)
          Index Cond: (target_project_id = projects.id)
          Heap Fetches: 419
          Buffers: shared hit=1381

The index also reduces the total query time to roughly 10 milliseconds.

GroupProjectsFinder#collection_with_user would run the following code:

    if group.users.include?(current_user)

When running this code for multiple groups this would result in one
query being executed for every group.

This commit simple removes the entire "if" statement with the code of
the "else" statement. This ensures both paths use the same code, and
removes the need for explicitly checking if a user is a member of the
group.

Disallow updating job status if the job is not running

Closes #46383

See merge request gitlab-org/gitlab-ce!19101

This reduces the number of queries necessary when displaying the
activity page of a group.

This was needed for a transition phase only. For details see #45389.

Closes #45389.
