action muxer: Fix gtk_widget_get_action_group

Browse Source 
The documentation for gtk_widget_get_action_group
and gtk_widget_list_prefixes states that both of
these operate on all the action groups that are
'available' to the widget.

Which means: they are meant to walk up the parent
muxer chain. So do that.

Add tests to verify the expected behavior.
