View Controller Introspection is Inconsistent

[rzulkoski]

I have determined there is a timing issue present when attempting to introspect a UIKit view controller.

Sometimes when UIKitIntrospectionViewController. updateUIViewController(_:context:) is called the view controller's parent is not set yet and its view is not in the view hierarchy yet (hasn't been added to the window). This means that there are times when the customization never gets applied because the selector failed to find the target.

UIKitIntrospectionView works around this issue by applying the customizations as part of a moveToWindowHandler set on the IntrospectionUIView.

I was able to fix this issue by updating UIKitIntrospectionViewController to also use its view's moveToWindowHandler when apply customizations. In addition, I updated both UIKitIntrospectionView and UIKitIntrospectionViewController to set their handlers up front in their respective makeUIView(Controller) methods rather than delaying it until updateUIView(Controller) is called.

See pull request #165

This has now been fixed. Thanks for getting this across the finish line @davdroman!

@rzulkoski no worries! I'll do some CI maintenance over the weekend and tag a new release by Monday.
