Changing the avatar of the user emits the changeUser event which triggers update of the system addressbook

Fixes #21513

Since we cache the generated avatars. We should also delete the
generated sizes when we remove the avatar.

Since we usually just get the avatar and stream the content to the users
there is no need to first create an image in memory.

* DI in avatar code
* Use the node API
* More unit tests
* Unit tests no longer require DB
