Sam Saffron 624184560e PERF: improve performance of publish_notifications_state
User.publish_notifications_state is called every time a notification is
created, this can become a very critical code path.

On some heavy notification related sites this can be a major CPU user on PG

This index makes it much cheaper to publish notification state, cause a
simple index lookup does the trick.
