Roll back only the decision's own Quest log entry and send stale-card decisions

A refused Try it now removes the Quest log entry it tagged when it added
it, so a read of the Quest log that landed during the decision is kept,
and reads the Quest log again since the decision may have been saved.

A decision is sent for the card thrown out even when a read of the deck
took it off during the exit, so Retry on that refusal posts the decision
again instead of failing before sending it.
