Fix more problems introduced by 6adb2ec

- Renamed canSendToAccount to canWithdraw, because the semantics are
  a little different from a payment. Notably, if withdrawing to self,
  you can still include a destination tag.
- Simplified the interface to canWithdraw to just pass in the
  STTx.
- preflightDestinationAndTag is pretty pointless now, so removed it.
