Remove hard crash when root view is reused

Summary: Alternative to D10499861. If an app does not have an exception handler, context.handleException will still hard crash. Since this error is just saying that we're reusing an unexpected RootView, it might be safe to continue execution. Let's remove the exception for now while we investigate further
