OPENJPA-370. Backing out the changes for the LoadFetchGroup implementation. We need to re-think the implementation (both the real and the expected). I left the test Entities in SVN, but removed the testcase so that we wouldn't fail the builds.

git-svn-id: https://svn.apache.org/repos/asf/openjpa/branches/1.0.x@591157 13f79535-47bb-0310-9956-ffa450edef68
