[DDC-1465] Fetching partial objects doesn't work if HINT_FORCE_PARTIAL_LOAD is not explicitly used

Using the DQL "partial" keyword is not enough to get a partial entity as a result.
The DQL hint HINT_FORCE_PARTIAL_LOAD must be used as well.

$q = $em->createQuery('SELECT partial r.{id,comment} FROM Entities\Rating r WHERE r.id=3');
$r = $q->getResult() /* HYDRATE_OBJECT is the default hydration mode */

Here, $r contains the full Entity, a SELECT * has been sent

$q = $em->createQuery('SELECT partial r.{id,comment} FROM Entities\Rating r WHERE r.id=3');
$q->setHint(Doctrine\ORM\Query::HINT_FORCE_PARTIAL_LOAD, 1);

$r = $q->getResult() /* HYDRATE_OBJECT is the default hydration mode */

Here, $r contains only the selected fields, hence a true partial Entity
