py34: test_hot and test_validate

Browse Source 
* use hashlib.algorithms_available in PY3 and hashlib.algorithms in PY2
* use e.args[0] instead of six.text_type(e) which will otherwise
  result in the unicode literal being flattened.
* add stubs to prevent actual API calls in tests.
* constraint the test template to help in more accurate testing which
  otherwise results in iterating through other unnecessary items.
