Allows to programatically set the default action without activating
the place mode:
 - vtkMRMLSelectionNode::SetActiveAnnotationID
Don't listen to unnecessary events like ActiveAnnotationIDChangedEvent,
AnnotationIDListModifiedEvent, InteractionModePersistenceChangedEvent.
Listening to ModifiedEvent is enough.
Todo: remove the unnecessary events.
