Subject: [PATCH] DATAJPA-956 - Fixed accidental pick up of
 non-EntityManagerFactor JNDI objects.

We now exclude all candidates beans that could theoretically become an EntityManagerFactory unless we definitely know so.

Previously bean definitions for JndiObjectFactoryBean that didn't expose an expected type (e.g. ones defined via JavaConfig) were propagated to the creation of a DefaultJpaContext.
