Title: Make the Illuminate\Http\JsonResponse class extend Illuminate\Http\Response

The `Illuminate\Http\JsonResponse` class doesn't extend the usual Laravel class, which is a bit tricky.
The only solution i could think of is to copy the `Symfony\HttpFoundation\JsonResponse` class and adapt it a tiny bit to restore the inhéritance `JsonResponse extends Response`
