Swapping homes stops announcing a body swap

SWAP HOME BASES traded homes correctly but borrowed the
positionsSwapped event, so the chronicle claimed the wizards
themselves changed places. It now speaks its own event — "swap home
bases — the maze's loyalties shift!" — and both hearths shimmer as
their allegiance changes.
