We saw in production that DispatchWorker was running about twice an hour,
which would schedule twice as many jobs as it should.

For some reason, BatchWorker was running 1000 times per hour, possibly
due to Sidekiq RSS kills that caused these jobs to restart.

Adding an ExclusiveLease prevents these jobs from running more
than they should.

[Rails5] Fix milestone GROUP BY query

Closes #48428

See merge request gitlab-org/gitlab-ce!20256

We need to preload the ancestors of search results after applying
pagination limits. This way the search results itself are paginated,
but not the ancestors.

If we don't do this, we might not preload a parent group of a search
result as it has been cut off by pagination.
