Reduce RankingUpdate calls on autogroup
If a new notification is posted that should be autogrouped, we can add
the group key _before_ we do a ranking sort, so that we don't have to
re-sort after we modify the notification with the autogroup attribute.
This should reduce the number of onRankingUpdate calls sent unnecessarily.
