DATACMNS-1121 - ProxyProjectionFactory now returns instance as is if it implements the target.

Browse Source 
If you previously asked ProxyProjectionFactory for a proxy of an interface which the target instance already implements, it created a proxy although it could've returned the instance as is. It's now actually doing that avoiding superfluous proxy creation.
