Obtains a DBusActionGroup for the action group which is exported at the given
bus_name and object_path.
The thread default main context is taken at the time of this call. All signals on the menu model (and any linked models) are reported with respect to this context. All calls on the returned menu model (and linked models) must also originate from this same context, with the thread default main context unchanged.
This call is non-blocking. The returned action group may or may not already be filled in. The correct thing to do is connect the signals for the action group to monitor for changes and then to call list_actions to get the initial list.
