Avoid returning all notifications to the client

[Donorhan]

What is the current behavior?

Currently the logged in user is subscribed to all the notifications he has, which adds server load and unnecessary data on the client side.

It would be great to return in priority the unread notifications as well as the read ones in order to have only 20 notifications max.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

What is the expected behavior?

What is the motivation / use case for changing the behavior?

Reduce client-side data and server load
