    tests: Remove stale symlinks before linking loop device
    
    On storage setup we can have stale symlinks to loop devices
    which were created before reboot and now are gone. Re-running the
    setup will fail on creating the symlink again. In this patch we
    add removal of the stale symlink, if there is such, before symlinking
    the new loop device.
