DATAJPA-867 - Upgraded to latest persistence provider dependencies.

Upgraded to OpenJPA 2.4.1 and Hibernate 4.2 build profile to 4.2.1. Added more snapshot profiles and register them for execution in the Travis build (Hibernate 4.2.next, 4.3.next, 5.next, 5.1, 5.1.next, Eclipselink.next and EclipseLink 2.7.next). Disabled Bundlor plugin for Travis build to make sure the OSGi-incompatible Eclipselink snapshot version numbers don't break the build.
