A wallet that lost the seat last sat in takes it back on load

The cap that dropped the newest seat left wallets without the very seat
their browser was sitting in, so a reload landed in the Peanut Gallery.
That seat is also kept on its own; loading the wallet now restores it
from there when it is missing.
