fix: a WRAP_ETH says where its ETH goes (closes #747)

A WRAP_ETH into the router now always reads `Moved to: The router`. That is
true whichever step then takes the WETH. Other takes keep
`The swap step that spends it`.

A later WRAP_ETH of CONTRACT_BALANCE to anyone but the router now gets a
`Moved from the sender` line reading `All the ETH the transaction carries`,
and `Moved to` names the recipient. It gets none after an UNWRAP_WETH into
the router, or while the router holds ETH from a V4 step.

README states both rules.
