    Testing failed for higher python3 versions
    
    When testing with python 3.6 our tests fail to run at all with...
    
      module 'unittest' has no attribute '__version__'
    
    With python 3.2 __import__ worked as we expected but in 3.6 running
    "__import__('unittest.mock')" provides the top unittest module rather than
    mock.
    
    Turns out the __import__ help info asks callers to never use it, and use
    importlib instead. Swapping over fixes this, and is still compatible with
    python 2.7.
