[FIX] mis_builder_cash_flow: Proper SQL expression + default for v13

- On v13, invoices are journal entries, so we have to explicitly exclude
  cancelled invoices from the expression. We leave draft ones, as they
  are good for forecasting.
- Default value for the company of the forecast line doesn't follow new
  specification, putting an incorrect value.
- Extra improvement: avoid a non needed casting of the fixed column type.
