If a user recieves 'this is your X edit' they should get this notif
regardless of whether the edit they created was deleted. We should
make sure the title is there only for deciding whether or not to
create a link for it; otherwise, the notification will just appear
without a link to the revision.

Don't try to render if page was deleted, and fix 'extra' parameter
(was breaking message key and thus rendering)
