    devtool/standard: Fix lock in _prep_extract_operation
    
    If for any reason the parse_recipe fail in extract command
    the process gets locked because Cooker is expecting the
    finish event by tinfoil.
    
    For example:
    
    $ devtool extract remake /tmp/remake
    
    ERROR: remake is unavailable:
      remake was skipped: PREFERRED_PROVIDER_virtual/make set to make, not remake
