ada: Missing adjust of controlled component initialized from container aggregate

In the case of controlled components initialized by a container aggregate,
the compiler was suppressing the call to the needed Adjust operation,
because it was suppressed for all aggregates. But container aggregates
aren't built in place, so target adjustment should still be done in that
case.

	component adjustment in the case of initialization by a container
	aggregate.
