The Skip* overrides in introspection are of the type "Do we skip? If not, then
I don't know, and we should call base", but the implementation of
iOSApiCtorInitTest.SkipCheckShouldReExposeBaseCtor is wrong, it just says to
not skip for every type except the one the method knows about.
So adjust the logic to call base if
iOSApiCtorInitTest.SkipCheckShouldReExposeBaseCtor has no knowledge of the
type in question.
