DATACMNS-376 - Repositories now inspects user class for factory lookups.

When looking up the RepositoryFactoryInformation for a domain type we now make sure we look up the user type to not accidentally try to do so for a persistence provider generated proxy class for the original type. This prevents us from not finding PersistentEntity instances, Repository- or EntityInformation accidentally.
