Ivan Kupalov 47fa775f21 Refactor notifications adapter (#985)
* Fix unnecessary reloading of notifications

This removes topId as it is not needed and just plainly uses status id
if needed. During initial loading of notifications topId/bottomId are
not set so we ended up reloading everything.

* Refactor notifications adapter

Use AsyncListDiffer for updating notifications just like in timelines.

* Cleanup in NotificationsFragment
