receive null itemId and lineItemId when merchant set item quantity
Our app receives broadcast for action ACTION_LINE_ITEM_ADDED,
and I receive orderId, itemId and lineItemId when an item is added to order
but if the merchant set the quantity (after adding the item) and the newQuantity > oldQuantity +1, then
I get null lineItemId (this one can be normal because we add more than one line item at ones)
and null itemId.
