FIX: Make sure topic_user.bookmarked is synced in more places (#13383)

When we call Bookmark.cleanup! we want to make sure that
topic_user.bookmarked is updated for topics linked to the
bookmarks that were deleted. Also when PostDestroyer calls
destroy and recover. We have a job for this already --
SyncTopicUserBookmarked -- so we just utilize that.
