    tpf-persona: use tp_connection_get_account()
    
    telepathy-glib introduced API to get the TpAccount of a TpConnection so Folks
    doesn't have to do it manually.
    
    This has the nice side effect of fixing a crash when TpAccount/TpConnection
    are momentary out of sync while connecting/disconnecting accounts.
