Api problem message as json

[weierophinney]

When I make request on non existing resource page /users?page=1234567 I receive:

{
  "type": "http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html",
  "title": "Conflict",
  "status": 409,
  "detail": "Invalid page provided"
}

As you see it a api problem. However in Content-Type you can find application/json instead of application/problem+json

Maybe good idea to add a test?

Another solution would be to include a

    /**
     * Does the payload represent a ApiProblem?
     *
     * @return bool
     */
    public function isApiProblem()
    {
        $payload = $this->getPayload();
        return ($payload instanceof ApiProblem);
    }

And use this method inside injectResponse method:

    if ($model instanceof HalJsonModel){
        if($model->isApiProblem){
            $contentType = 'application/problem+json'
        }elseif($model->isCollection() || $model->isEntity()){
            $contentType = 'application/hal+json';
        }
    }
