[FW][FIX] sale, purchase: fix invoicing interaction with “Invoicing Switch Threshold”

Steps to reproduce

Create a sale order with a product that's invoiced on delivered quantities.
Set delivered quantity (partial delivery) and create an invoice based on the delivered quantity. Set the "Invoice Date" to sometime in the past.
Go to the settings and set "Invoicing Switch Threshold" to any date in the future (so that the invoice you created has a date BEFORE the new threshold)
The invoice will get the label "invoicing app legacy".
Go back to the sales order and change the delivered quantity.

You should see that the invoiced quantity is automatically set to 0.
A similar behavior can be observed with purchase orders.

Why this is happening

When a new “Invoicing Switch Threshold” is set, all posted invoices before the threshold are marked as canceled. In v15, changing the delivered quantities triggers the invoiced quantities to be recalculated as well. However, computing invoiced quantities doesn't take into account invoices that are marked as canceled. This mean that the newly computed invoiced quantities won't include invoices posted before threshold.
