    Clean tempest dir before cloning.

    This ensures that the code is recloned and if a venv is used, it is
    unpacked into a clean clone. If a venv is unpacked multiple times (eg
    multiple runs of the playbook) into the same dir then that venv may
    become inconsistent.

    This is a minimal fix for liberty as the full patch didn't backport
    cleanly.
