OPENDJ-2460: fix pluggable backend unit tests This was evil. TestNG has a bug which prevents method dependencies from working with inheritance. When looking to see if another test method has already completed it sometimes looks in the wrong sub-class instance, when it should look in the current sub-class instance I tried to refactor the JE/PDB tests to use @Factory for creating test instances (one for PDB one for JE), but both instances end up being invoked in parallel. In order to preserve the ordering I tried using the "priority" @Test attribute, but it did not work. I reordered the test methods and ran them sequentially, but TestNG ignores the declaration order and just runs them in alphabetical order. Finally, I refactored the tests so that they have no side-effects and can be run in any order, which was probably the right thing to do anyway.
