    'async' SyntaxError with python 3.6 and above
    
    Python 3.6 adds a couple new keywords to the language (async and await) so we
    need to be careful not to use those. 99.9% of our users don't import our test
    utils so this was mostly moot, but Juan ran into an issue packaging Stem for
    Fedora...
    
      BUILDSTDERR:   File "/usr/lib/python3.7/site-packages/stem/util/test_tools.py", line 151
      BUILDSTDERR:     self.method.async = self
      BUILDSTDERR:                     ^
      BUILDSTDERR: SyntaxError: invalid syntax
    
      https://trac.torproject.org/projects/tor/ticket/26739
    
    This line aimed to provide a way for tests to reference its AsyncTest instance.
    This doesn't look to actually be used in practice so think we can simply drop
    it. Checked with grep and a 'run_tests.py --all --target ONLINE' run.
