REVISION SUMMARY
  I broke the py2 version in https://phab.mercurial-scm.org/D9287
  because the `WorkerError.__bytes__()` (or `.__str__()`?) output was
  different in py2 compared to py3. Part of the problem was that I
  didn't propagate the status code that was passed in to the superclass
  so it could get printed. This patch fixes that. I don't know how it
  worked on py3 before this patch...
  
  I also added the usual `__bytes__ = _tobytes` override for good
  measure. It doesn't seem to be needed for tests to pass, though.
