Incorrect link between stock move on invoice line

We noticed something strange when cancelling a supplier shipment and using modules "purchase_invoice_line_standalone" and "account_invoice_stock".

To reproduce:

• Create a purchase (with one purchase line) and process
• Create a supplier shipment for this purchase
• Receive shipment -> purchase_invoice_line is created and linked to the incoming move

• Cancel shipment -> another purchase_invoice_line with negative quantity and no link with stock_move

• Handle exception on purchase to recreate shipment-> a new incoming_move is created

This new incoming_move will be linked to the purchase_invoice_line with negative quantity!

• Create a supplier shipment for this purchase
• Receive shipment -> another purchase_invoice_line is created and linked to the incoming move

So we will have 3 purchase_invoice_lines:

• one purchase_invoice_line linked to the cancelled incoming_move
• one purchase_invoice_line with negative quantity linked to the new incoming_move (should be the cancelled incoming_move or None)
• one purchase_invoice_line with positive quantity linked to the new incoming_move
