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.
