    Don't announce removal of Individuals twice.
    
    Before this patch, we would announce an Individual's removal, "dispose" of the
    individual, then announce their removal again (at which point they would have
    zero Personas, which can make it harder for clients to do anything useful with
    the notification anyhow).
