    Fix some races in the chatroom joining code
    
    The auto-reconnection logic for chatrooms was a bit odd. It would for
    every chatroom that existed when the account manager was prepared
    connect once to status-changed for each account for each chatroom...
    
    Change this such that whenever an account connects, we simply
    get the then current list of chatrooms and auto-connect those as needed.
    
    This fixes issues when a chatroom gets removed from the manager and when
    the auto-connect options on a chatrooms change.
