DATAJPA-472 - Verify that pagination works with entities with @IdClass.

This works as expected with  3.6.10, 4.2.10, 4.3.4 but fails with  4.1.12.
Added test case to verify and track the issue with Hibernate 4.1.x.
Renamed test-class from DataJpa269RepositoryWithCompositeKeyTests to RepositoryWithCompositeKeyTests.
