Temporary hack until notice_profile_id_idx is updated
to (profile_id, id) instead of (profile_id, created, id).
It's been falling back to PRIMARY instead, which is really
very inefficient for a profile that hasn't posted in a few
months. Even though forcing the index will cause a filesort,
it's usually going to be better. Even for large profiles it
seems much faster than the badly-indexed query.
