ada: Fix internal error on aggregate nested in container aggregate

This handles the case where a component association is present.

gcc/ada/

	* exp_aggr.adb (Convert_To_Assignments): In the case of a
	component association, call Is_Container_Aggregate on the parent's
	parent.
	(Expand_Array_Aggregate): Likewise.
