DDC-2550: Inverse side of x-to-one can never be lazy

Jira issue originally created by user hosiplan:

Here is a note that "Inverse side of x-to-one can never be lazy"

https://github.com/doctrine/doctrine2/blob/29d6da0fa063d55d06117045f3446b2716202d2b/lib/Doctrine/ORM/UnitOfWork.php#L2587-L2588

I don't understand, why there cannot be a proxy. But ok, let's say that for some internal implementation reason there canno be a proxy yet. That means there should be at least an exception raised, when validating schema, telling me this crucial information.

Doing a select over 500 entities would result in 501 queries just because I didn't know about this.
If the validator would tell me, I'd join the entity and had 1 query executed.

Resoltion: you shouldn't allow me to define the association as lazy, or use proxies.

Thank you.
