Fix interactivetool python 3 support and tests

- enables docker destination for interactivetool tests
- fixes a wrong argument in entrypoint management
- fixes the test setup that targeted a previous iteration (which was
  still called realtimetools)
- prevents deleting the working directory before python has a chance to
  start the container monitor (that's the sleep command)
- fixes some odd interactive tool test assertions
- uses unicode arguments in key_type_token_mapping.py.
  uwsgi arguments are always passed as bytestrings.
