Konstantin Podshumok 9b2aac9e5c [MRG + 1] [TST] (half-cosmetic) use less nose.tools import to simplify future transition to py.test (#7384) 
* use less nose.tools import to simplify future transition to activly developing test suites/runners

* there was no assert_dict_equal in py2.6. but we can use assert_equal

although failed test will look a little bit ugly
