Log Message:
Update to 1.2.1. From the changelog:

- Updated all the live engine tests, aside from Oracle, to test with
  unique registry names, so as to avoid conflicts when multiple
  instances are being tested at once. Thanks to Slaven Rezić for the
  report (#597).
- Removed `local` directory from the distribution, accidentally included
  in v1.2.0. Thanks to gregor herrmann for the report (#600).
