py3: return unicode from setup.py's get_version

py3 expects the version number for eggs to be unicode, so despite 9.2.0 being
the first evolve release with beta py3 support it isn't currently pip
installable since it dies with:

    File "*/setuptools/command/egg_info.py", line *, in tagged_version
      return safe_version(version + self.vtags)
  TypeError: can't concat str to bytes

The `setup.py install` test added in a previous commit should cover this since
it died in a different but similar way before.
