While calling `_stock_account_prepare_anglo_saxon_out_lines_vals`, the line
`credit_expense_account = accounts['expense'] or self.journal_id.default_account_id`
can cause a 'Expected singleton' error. During upgrades from v13 and earlier,
the value used for `accounts['expense']` is always `None`.
If the recordset in `self` contains more than one record, the error will happen.
By replacing `self` with the iteration object `move`, this error is averted.
The error happened during an upgrade from v13. Since the value assigned to
`accounts['expense']` doesn't exist in that version, it goes to
`self.journal_id.default_account_id` to grab it.
If `self` has more than one record, the error happens.
Traceback:
