    fractal-gtk: room_history: Don't group messages if redacted
    
    If the previous message has been redacted don't group the messages.
    
    This fixes an issue where a user can post a single message, resuling in
    their name and message appearing. Then a user can redact that message,
    removing their name and message. Finally they can post a new message
    where only the message but not the name appears.
    
    This commit has the downside that if a user redacts a message in the
    middle of multiple messages their name will appear redundantly. These
    will be fixed by "refresing" the room, by either swapping rooms or
    restarting Fractal.
