Andreas Traczyk 4bda330637 swarm: simplify and update avatar update mechanism
Implements a leaner avatar caching system. The avatar component
listens for uid filtering its id, which may be:
- conversation id
- account id
- contact uri

In response to the uid change, a the image source is updated with
a new image url invoking a fresh QQuickImageProvider query. With
this design, only the avatarregistry's uid mapping needs to be
updated when profiles are changed, and no longer should specific
avatar components receive manual source updates.
