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
taking a long time to load because they were loading every ActiveRecord
of the user-accessible projects into memory. This change modifies so
that only the IDs are loaded into memory.
Closes#23684

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.
Closes#23668
