Description of Change

Fix ModalNavigationManager so it will reprocess the current Modal stack when the root window handler changes. Currently we aren't processing any modal pages pushed before the app has loaded and we don't reprocess the modal stack if the window is destroyed and recreated (Android).

This PR adds code to detect when we need to reprocess the modal stack based on the root view changing or being destroyed

Should this rather be an interface if it does not do anything specific?

Perhaps eventually?

At some point we'll move modals into core and those APIs will all get designed. There's not really a larger use case here yet for an interface so I don't think we need to make that leap yet.
