fix(specs,tests): Fix withdrawal tests for BALs issue with idx==0

- `self.txs.successfully_parsed` is a list of transaction indexes, not
  transactions. The "if tx" check here would then check `if 0` which
  parses as a boolean ``False``. This means we would skip counting the tx
  if index=0 was successful.

- Fixes some test expectations where `post_code` was being checked instead
  of ``new_code``.
