Notifications on changed notes are not superseeded

[christianlupus]

Please make a clear and concise description of what the bug is.

Steps to reproduce

1. Have two users A and B with access to a NC instance
2. Share a folder (e.g. Notes) from B to A
3. On B's settings enable notifications via mail/feed on changes to notes/files.
4. Create multiple change events using user A on some notes (multiple changes in the same note)

Expected behaviour

User B gets notified about an updated file as notification. The same vice-versa.

Actual behaviour

User B is bombed with notifications as every change is transferred into a notification.

E.g. if user A is on shopping tour and just checking the todo list entries, this will trigger dozens of notifications for user B.

I tried to reproduce but #1375 blocks this somehow.
