Fix problem when deleting multiple topics from a forum in bulk. We getting a list of topics from the database, then deleting each topic. But after you delete a topic, the forum.last_post on the remaining non-deleted topics can be stale. This was causing a weird DoesNotExist. Now just get the topics one at a time from the database.
