FIX: Ignore posts needing approval when calculating reviewable counts. (#13464)

In #12841, we started setting the ReviewableQueuedPost's target and topic after approving it instead of storing them in the payload. As a result, the reviewable_counts query started to include queued posts.

When a category is set to require approval, every post has an associated reviewable. Pointing that each post has an associated queued post is not necessary in this case, so I added a WHERE clause to skip them.
