Fix filtered search issuable empty state exception
What does this MR do?
Fixes exception that was causing code execution to stop, which lead to subgroup titles not appearing for issuable index pages that were empty (and thus didn't have a .filtered-search
selector available).
Adds tests.
Are there points in the code the reviewer needs to double check?
