    Requiring mock version 0.7.0 or later
    
    Our jenkins tests presently have mock version 0.6.0, but we're using mock's
    patch.dict which was introduced in 0.7.0. This causes the tests to fail with...
    
    Traceback (most recent call last):
      File "./run_tests.py", line 394, in <module>
        main()
      File "./run_tests.py", line 173, in main
        for test_class in test.util.get_unit_tests(args.test_prefix):
      File "/srv/jenkins-workspace/workspace/stem-tor-ci/test/util.py", line 130, in _get_tests
        module = __import__(module_name)
      File "/srv/jenkins-workspace/workspace/stem-tor-ci/test/unit/version.py", line 20, in <module>
        class TestVersion(unittest.TestCase):
      File "/srv/jenkins-workspace/workspace/stem-tor-ci/test/unit/version.py", line 22, in TestVersion
        @patch.dict(stem.version.VERSION_CACHE)
    
    Making run_tests.py balk if we're using a version of mock prior to 0.7.0.
