    Delete python bytecode before every test run

    Because python creates pyc|pyo files and __pycache__
    directories during tox runs, certain changes in the tree,
    like deletes of files, or switching branches, can create
    spurious errors.

    The target bytecodes for deletion are in normal directories,
    but not in dot started directory.
