Message:

This PR fixe a edge case when hydrating an existing object which already has a proxy to diff��rente entity.

Imagine the entity

/*** @ORM\Entity() **/
class User
{
    //...

    /*** @ORM\ManyToOne(targetEntity="Address", fetch="EAGER") **/
    private $address;

    //...
}

/*** @ORM\Entity() **/
class Address
{
}

When a instance of User has an address created with a Proxy, then, the hydratation of an other instance of the same User will replace the content of the field address in this instance.

Such situation append with a PUT call with the DunglasApiBundle and the validator UniqueEntity from Symfony which trigger a $repository->find on the object.

First the entity is loaded from the entityManager (which store the reference in the identityMap of the uow
Then the serializer overrwrite the entity, and may create reference for the related properties
Then the object is validated before flushing which trigger the UniqueEntityValidator

How to reproduce:

$user = $repository->find($id);
var_dump($user->getAddress()->getId());
// 1337

$user->setAddress($em->getReference('Address', 42));
var_dump($user->getAddress()->getId());
// 42

$somethingElse = $repository->find($id);
var_dump($user->getAddress()->getId());
// 1337
