Advise a recheck for an unanswered check on a ready or rejected delivery (issue 451)

That check answered once, so the build queue is the wrong place to look.
mesh-delivery names the delivery's state as data (held); the controller
reads it and never the words. A line without it keeps the advice of 438.
