JsonResponder and TwigResponder don't respect status set in payload

[dropdevcoding]

In JsonResponder the status set in payload is not respected, since it's implemented like that:

return $response->withStatus(200);

This should be fixed by using the same logic used in other responders:

$status = $payload->getStatus() ?: 200;
return $response->withStatus($status);

Good catch!

I recently detected the same problem in TwigResponder
