"Not yet implemented" unittests

[buhtz]

I found some TODO-like comments and hints in the code about "Not yet implemented" unittests. I wan't to keep that notes but not in the code. Currently they produce skipped tests which is IMHO not OK. All tests should be anything else then green. I'm a bit pedantic here. 😃

Just as an example how this looks like

@unittest.skip('Not yet implemented')
def test_inhibitSuspend(self):
    pass

@unittest.skip('Not yet implemented')
def test_unInhibitSuspend(self):
    pass

So I moved that TODO's in that Issue
