Retain the current room member avatar when renaming

Closes #481. Note: the library doesn't even have the API in User
to set per-room avatars; one still can achieve that by calling
Room::setState<RoomMemberEvent>(...) though (and it's likely to be _the_
recommended way to deal with per-room user profiles in 0.7, with User
being entirely deprecated).
