nisse-review: a review refused for an open point posts once the point is answered

On #166 the reviewer called post_review with two points unanswered, was
refused, answered them, then only skipped already-answered points until the
40-turn cap: the review went out as partial, its summary lost. A refused
ending call is now held, and the driver ends the run with it as soon as the
last point is settled (a new due hook in nisse-core's driver; nisse-dev
doesn't use it). A held call that is wrong for another reason by then
(sign_off over drafted comments) is left to the model. With nothing open,
reply and skip say which tool ends the run.
