Use assertEqual() instead of assertDictEqual()

In unittest2, assertDictEqual() is implemented by
using != operator to compare two dicts. So is
assertEqual() in testtools. assertEqual() in
testtools is able to handle dict, list, set and
so on. So we just call assertEqual() to make the
unit tests simpler.
