I discover that computeChangeSet doesn't compute as before from this commit:

53a5a48aed (commitcomment-5696972)

From this commit, I have a bug when using KNP doctrine behaviors (with a custom code to log the changes on Entities in Database) because when I call the following code, it doesn't return the same changeSet as before:

$uow->computeChangeSet($classMetadata, $entity);
$changeSet = $uow->getEntityChangeSet($entity);

Before the "ManyToMany" properties were not in the $changeSet. Now there are with original value NULL -> new value Doctrine\ORM\PersistentCollection. Is it normal?
