[FIX] mrp, purchase_mrp: purchase_line_id also with kits

When confirming a move for a kit, it is basically unlinked and replaced
by moves for its component. The link to the purchase line was kept in
v10, but since rev[1] it is not anymore. Make an helper to get the
values and override it in purchase_mrp to add the purchase line link.
