DDC-822: Query with detached Entity as parameter fails to execute

[doctrinebot]

Jira issue originally created by user nicokaiser:

When dealing with detached entities, e.g. with the QueryCache, you cannot use these entities as parameters for other Query.

Example:

$em->detach($user);
$query = $em->createQuery('SELECT a FROM Address a WHERE a.User = ?1');
$query->setParameter(1, $user); // $user is detached

As $user is detached, the EntityManager does not have its identifier, so Query::_doExecute fails. (There is a "//TODO: Check that $value is MANAGED?" line near the failing line).

This patch should fix Doctrine\ORM\Query to work with detached Entities.
