update EclipseLink/OpenJPA test case to filter out javax.persistence classes

JBoss modules is improving the case when two modules have bi-directional dependencies (a depends on b and b depends on a). Part of this is ensuring that module level classes are used over classes from dependencies (child first).

This jira is about fixing this for two of our unit tests that willl have this problem (an EclipseLink + OpenJPA static module test).
