Fix bug when priming references nested in embedded documents

[chapa]

Fix bug that occur when you have a schema like this :

/** @ODM\Document */
class Document
{
    /** @ODM\Id */
    public $id;

    /** @ODM\EmbedOne(targetDocument="Embedded") */
    public $embeddedDocument;
}

/** @ODM\EmbeddedDocument */
class Embedded
{
    /** @ODM\ReferenceMany(targetDocument="Referenced", name="referenced_documents") */
    public $referencedDocuments;
}

/** @ODM\Document */
class Referenced
{
    /** @ODM\Id */
    public $id;
}

And you execute a query like this :

$qb = $dm->createQueryBuilder('Document')
    ->field('embeddedDocument.referencedDocuments')->prim(true)
;
$documents = $qb->getQuery()->execute();

I think it also occur if you change @ODM\EmbedOne to @ODM\EmbedMany and/or @ODM\ReferenceMany to @ODM\ReferenceOne.
To be sure, I test it all in ReferencePrimerTest.php

Hey !

Sorry to bring out this closed PR, but I just notice I forgot to remove 3 lines of annotation there.
If anyone who is making a useful commit would like to remove them, he's welcome ;-)

Thanks for pointing that out! Luckily not big deal ;)
