Title: FIX: avoid a rare NULL pointer segfault

I'm not a hundred percent sure about this one; it might be caused by another bug, possibly only in my local tree. However, I did see segfaults when dismantling a passenger transportation network by selling all the vehicles, and this patch should deal with the case where connexions[0] no longer contains a valid connection to the intermediate target.
