DDC-1732: Unserialized non-initialized proxy classes should throw an exception when a method is called

[doctrinebot]

Jira issue originally created by user benjamin:

When we serialize entities in a session, we often have pointers to uninitialized proxies. These proxies have $_entityPersister == null.

The problem is that if you happen to call by mistake a method on such a proxy, you're not aware that this is an uninitialized proxy, and the business methods are called, with null values for every property.

I think the proxy should throw an exception in that case. Attached, a patch with the proposed modification.

@Ocramius I think it can be closed as invalid

@malukenho this is probably still valid, and would need patching, or at least testing.
