    Remove times.dbm file for each tox run

    If you run the py27 tox tests then attempt to run the py34 tests,
    the following error will occur:

        running testr
        running=OS_STDOUT_CAPTURE=${OS_STDOUT_CAPTURE:-1} \
        OS_STDERR_CAPTURE=${OS_STDERR_CAPTURE:-1} \
        OS_TEST_TIMEOUT=${OS_TEST_TIMEOUT:-60} \
        ${PYTHON:-python} -m subunit.run discover -t ./ ./ --list
        db type could not be determined
        error: testr failed (3)

    This happens because the apparently the times.dbm file generated
    by py27 is not compatible with py34. The converse is not true though -
    if you run py34 first, py27 will work.

    Both these bugs have been filed against it, but I see no resolution

    https://bugs.launchpad.net/testrepository/+bug/1229445

    The work-around is to delete the file, which is what is now done
    before running every tox test. Once the bug has been fixed, the
    work-around can be removed.
