Idiot lifts the moment its march turns impossible

The all-carried check ran only on the victim's own step, so a curse
whose last floor treasure was hauled off mid-turn kept its grip until
the idiot happened to move. The lift check now also runs at the pickup
that empties the floor, and at attach for a victim already standing on
their chest.
