[IMP] For subcontractor total qty on invoice line

To avoid quantity difference between invoice line and subcontractor, we copy the quantity from subcontractor to invoice line (if diff is really small), this way, we avoid amount differences between the invoice line and the subcontractor. On the other hand, we loose a bit of accurency between invoice line and timesheet line.
