TRUNK-3868 - Combine PatientDAOTest and HibernatePatientDAOTest 

Merged the differences between PatientDAOTest and HibernatePatientDAOTest into PatientDAOTest. There was only one test in  HibernatePatientDAOTest that was no present in PatientDAOTest.

If wanted, I can delete the HibernatePatientDAOTest in a new commit.

See the ticket: https://tickets.openmrs.org/browse/TRUNK-3868

Thanks.
