[FIX] stock_move: show source document

Install stock and sale. Create a sale with 2+ products, save and
confirm.
Look for the created picking.

There will be no source doument, because of
cb618e9a99ea3b86fdeed0295168a1e9fd7cddc3
the behavior has changed when there are multiple source
document, possibly to avoid displaying the wrong source if they
differ.

Adding the possibility to display multiple source documents, eventually
truncating the list
