createNavigationContainer: rethrow the error instead of creating a new one (#4533)

Creating a new error makes the stack unreadable in sentry, because the stack is stringified when the error is cast to string to create a new one.
Is there another reason to do that ?
Alternative possible solution would be to add a method to be able to handle the error ourselves ?
