Fix skipping properties if they are listed after a not loaded relation.

[lenardpalko]

This issue fixes an issue that occurs when merging entites, when the entity that is being merged has some other properties after a association type field.

Fixes the following scenario :
Your entity extends a parent entity and when it is merged by the entity manager first its fields are computed, this is done correctly bby ReflectionPropertiesGetter::getProperties(), but in the mergeEntityStateIntoManagedCopy method the iteration is stopped when it gets to a field that is a relationship and it is Proxy and was not loaded yet.
The order in which the fields are computed is : current class properties and then the parent properties, so if the current class has a lazy loaded relationship then the properties of the parent are not merged.

So the fix doesn't stop the iteration it just skips the current property that is not loaded yet and goes to the next property.

This sounds like one of those fiddly edge-cases where a test may be useful.

yeah requires a test case indeed

I've added some tests too. Not sure if the location is appropriate, let me know and I move them. I've added them under the namespace Doctrine/Tests/ORM/Functional/Ticket.
