configschema: fix various issues with NestedTypes 

A handful of bugs popped up while extending the testing in
plans/objchange. The main themes were failing to recurse through deeply
nested NestedType attributes and improperly building up the ImpliedType.
This commit fixes those issues and extends the test coverage to match.
