Fix timeout when checking group dependencies (17.3 backport)
What does this MR do and why?
This MR is the 17.3 backport for !162857 (merged)
In !161215 (merged) we
migrated the dependency list empty state to use a new database query.
This query checks a column which is only covered by partial indexes with
a WHERE archived = false
clause. We forgot to include this scope on
the new query which causes it to have no index coverage so it attempts
to scan the entire table and times out. We only show dependencies from
unarchived projects on the depenency list so the correct behavior is to
only check for existence of unarchived dependencies. This fixes the
timeout as the query can now utilize partial indices.
Fixes: #479300 (closed)
