conversations: set fallback avatar's color based on known username
- Sets the conversation cells' fallback avatar colors based on
the username known when initializing. This should avoid the
color flickering except when a lookup is actually in progress.
- Uses the value of the username known at cell init to set
the fallback avatar's intitial.
- Removes the use of the fallback avatar initial in the case of
the ringId being the best name. For now, no character is shown.
