When the account is put online automatically, for instance to make a channel request or because network connectivity becomes available, the automatic presence type, status and message will be copied to their "requested" counterparts.
One can receive change notifications on this property by connecting to the notify signal and using this property as the signal detail. Change notifications for automatic-presence-type, automatic-status and automatic-status-message are always emitted together, so it is sufficient to connect to one of the notification signals.
This is not guaranteed to have been retrieved until prepare_async has finished; until then, the value is UNSET.
