Multiple notifications are triggered with activity app

[christianlupus]

If the activity app is enabled, each modifiaction is registered as an individual activity. This causes the notification app to going havoc if you change a shared note in regular but short intervals.
Concrete example: A shared shopping list with checkboxes can be checked in the app or the web frontend while shopping. This causes me to see like 20 to 50 notifications I have to drop in order to see the important ones.

Steps to reproduce

1. Have a NC instance with activity and notification app enabled
2. Have file notifications enabled in feed (and optionally as mail)
3. Share the notes folder of user A with user B
4. As user B set storage backend to the shared folder
5. As user B open a note (or create one) and modify it
6. Wait a bit or close the note
7. Continue writing

Expected behaviour

The user A is informed that the file has changed.

Actual behaviour

Each change is represented as a file written thus adding multiple notifications to the list.
