Prepare field's value for references

[malarzm]

This is a subset of ODM preparing query according to field's mapping, but as it's bigger thing here's small part that is cool enough to make its way to 1.1 already - now one can query for references without using query builder! It even doesn't matter if reference is one or many, simple or not:

$dm->getRepository(User::class)->findOneBy(['account' => $account]);
$dm->getRepository(User::class)->findBy(['groups' => $group]);

Additionally to being nice it should fix doctrine/DoctrineMongoDBBundle#208 and close #292 :)

Wow, so simple one could ask why we haven't thought of this before. Does this also work in query builder or does that still have to go through reference?

$queryBuilder
    ->field('account')
    ->equals($account);

Should work already, but won't be as smart as references after #1333 and I'm not sure yet whether it should :)

👍 Sounds good!
