NPE during SessionFactoryImpl init when 2L caching is enabled and @NaturalIdCache is used with EHcache
------------------------------------------------------------------------------------------------------

                 Key: HHH-7089
                 URL: https://hibernate.onjira.com/browse/HHH-7089
             Project: Hibernate ORM
          Issue Type: Bug
    Affects Versions: 4.1.0
            Reporter: Eric Dalquist


The org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory always returns null for buildNaturalIdRegion due to an oversight during work on HHH-6974

The result is that if Second-Level caching is enabled and any entity is annotated with @NaturalIdCache session factory creation fails with a NPE
