Say loudly when a condition that needs the operator could not be asked on any channel (hq ADR 0259)

With no router, or an ask the router refused and nothing changed since, the controller asked nothing
and said it only in its own log. It now keeps a condition of its own, asks-undelivered, naming the
conditions not asked and why, cleared once each can be asked again.
