[PATCH] Take care also of the KJob::finished signal in KPart - it also fixes Ark's BUG 187538

The attached patch is the same I've uploaded to the reviewboard
request. It fixes KUiServerJobTracker by introducing a new protected
slot that calls kill(EmitResult) as suggested by David Faure and in a
certain way by Aaron Seigo too.

It's not very efficient because it calls QHash::keys -- actually, I'm
not sure if we need to call keys() and then have that Q_ASSERT or we
can rely there's only one job with that jobview and call key()
directly.

Is this OK?
