python tools - variable not initialized

[tulinkry]

Command output in project 'xxxxxxx' contains errors:
  sudo -u tulinkry opengrok-mirror -c /Users/tulinkry/workspace/tulinkry/OpenGrok/local/mirror-config.yml -U http://localhost:8080 r3
    Traceback (most recent call last):

I see the same warning in IDEA.

Technically, this is not a problem since the worker() will only use logdir if batch is true and __main__() has this:

    # Log messages to dedicated log file if running in batch mode.
    if args.batch:
        logdir = config.get(LOGDIR_PROPERTY)
        if not logdir:
            fatal("The {} property is required in batch mode".
                  format(LOGDIR_PROPERTY))

It should be sufficient to initialize logdir to None.
