Leo Hemsted 2355ee011f log more info when we receive multiple delivery callbacks for one notification
Previously, we logged a warning containing the notification reference
and new status. However it wasn't a great message - this new one
includes the notification id, the old status, the time difference and
more.

This separates out logs for callbacks for notifications we don't know
(error level) and duplicates (info level).
