Two client errors had a wrong status with Laravel:

• an IRI that matches no route ({"author": "/api/nope/1"}) gave a 404, the NotFoundHttpException of the Laravel router went through. Router::match() now throws the RouterInterface exceptions and the IRI converter turns them into an InvalidArgumentException, like on Symfony.
• serializer errors (a wrong type in the body, an invalid IRI...) gave a 500, the Laravel defaults of exception_to_status only had the auth exceptions. I added the same 400 defaults as Symfony, plus a fallback in the error renderer for apps that already published their config.
