Do not show unsubscribed email subscriptions in notification settings
With changes in !1191 (merged) email and bell subscriptions are handled differently by now. In settings there is a menu point "notifications" (=Benachrichtigungen). This allowed to disable a description in the past – which is still working. With current changes the disabled entry isn't removed anymore. Previously it was removed after saving.
Currently subscribing to a bell would create an disabled email entry there.
Restoring this behaviour is quite easy:
Find getForumThreads
with full text search and change this SQL query to only list email subscription. Also consider renaming the only being used here method to a better fitting name.
DB: fs_theme_follower.infotype
In the long run it might make sense to also provide these settings for bell subscriptions (not sure) but I consider this a nice small step which should be taken before.
