allow paramfetcher to try and fetch parameters from forward call

Hi, it seems this is needed to be able to fetch parameters, coming in via a controller forward, eg:

````
$this->forward('AcmeApiBundle:Entity:get', array('id' => 'd22484bf-1d48-11e4-a4e4-a45d36c13021'));
````

is coming in as :
````
object(FOS\RestBundle\Controller\Annotations\QueryParam)[501]
  public 'name' => string 'id' (length=2)
  public 'key' => null
  public 'requirements' => null
  public 'default' => null
  public 'description' => string 'Get an object by id. Format: uuid .' (length=35)
  public 'strict' => boolean false
  public 'array' => boolean false
  public 'nullable' => boolean false
````

am i doing something wrong ?   why is it coming in as a QueryParam, should this be a requestparam ? 

Thx in advance.
