REVISION SUMMARY
  In cases where the root commit is empty commit, None will be returned as
  parents. This was implemented by https://phab.mercurial-scm.org/rHG2c13e91ede6e646aa667be722b02375368df9187.
  
  This breaks test on py3 because `b'%s' % None` does not work. It does not matter
  whether we return `None` or `'None'` as we skipped converting to svn step by
  doing an early return. So let's return `'None'`.
  
  I tried to patch all the users to convert `None` to `'None'`, but there were
  more users than I expected. I hit 3 of them and decided to fix it this way
  around.
