[FIX] Account for users without an avatar or group

1. Ensure new users belong to an Agent

Users may come without the correct group information, leading
to a situation where they have no Agent assigned to them.
The application cannot handle this, so we ensure new users
are at least associated to the new Anonymous Agent.

2. Introduce a default avatar

Users coming without an avatar would see a broken view.
Now they're assigned a default avatar, which shows the IN COMMON
icon logo instead.
