orderline quick input follow-up

[metas-lc]

• sales order:

• batch entry - adding same product multiple times: once i get the product with HU (e.g. HU x 10), once with "No Handling Unit" NOK
• add new - orderline takes the one from trading unit field (trading unit field is virtual pi by default - won't change, but i think this field should not be here) NOK
• batch entry when is no HU for the product+bpartner - once with "No Handling Unit", one with "Virtual PI" NOK

• purchase order:

• batch entry - adding same product multiple times: you will always get the HU set on product (e.g. HU x 10), even if the HU is for another bpartner NOK
• add new seems to work fine OK
• not sure if wanted, but trading unit field is not shown in purchase order line NOK?

NOTE: you can see "No Handling Unit" in results because there is a packing item which is called like that, a different one from the actual "No Handling Unit".
