Pavlo Shchelokovskyy 594dd453a8 Fix comparison with singletons ... Many plases in tests code use assertEqual(AA, None), the same with True and False and negatives of such comparisons. As comparison to singletons must use `is` operator, appropriate usage is assertIs, assertIsNot, assertIsNone, assertIsNotNone These assertions are provided by the `testtools` package, so this change is not breaking backward compatibility with Python 2.6 This second patch inlcudes the other half of the files touched by these changes to ease the review.
