The below revision force the use of `ABS` on the
`price_subtotal_signed` because of a migration issue:
649b289fa1
This leads to issues regarding the advances, in
`out_invoice` invoices, where this amount
`price_subtotal_signed` is negative, and should
remain negative in this report, otherwise
the advance is counted twice: Once with
the advance invoice, and a second in the actual
invoice where the advance is removed with a line
with a negative `price_subtotal`
e.g.
- A sale order of 500€ without taxes
- Create an advance invoice for an advance payment of 10%: 50€ without taxes
- A second invoice with the remaining: 450€ without taxes
In the invoices report, the total without taxes for this customer was
displayed as 600€ (50 + 500 + 50)
instead of 500€ (50 + 500 - 50)
