Draw the author's picture beside a received bubble

Reported: profile pictures do not appear in the chat boxes. They did not.

iOS had an avatar slot in MessageBubble that hand-rolled only the initials
fallback - it never had the user id or the inbox, so it could not reach the
picture that AvatarView already downloads and decrypts everywhere else.
Android reserved the kit's 40dp received inset for an avatar and drew nothing
in it at all.

Both now pass the author and the picture through. Sent bubbles get none: you
know who you are, and a picture on both sides halves the width a thread has.

Also gives the iOS list row a real last-message preview and a timestamp,
matching the Android row - it was showing a screen name and the word 'Online',
a second copy of the dot already on the avatar.
