Fix variable choice in NotificationController::notify
Fix variable choice in NotificationController::notify

I believe this is a bug. Individual user's option ($userNotifyTypes)
should not influence the options for all users ($notifyTypes).

This piece of code was first introduced in
I51600bbb26594323831d22bc35d34587ff146d47.
