Bug 34736: Don't trigger quantity change on loading order

Bug 34736: Don't trigger quantity change on loading order

We have a change event to automatically check or uncheck the first items on a list when
the value is changed directly.

The code is calling this when setting the quantity when loading an order, but this is causing a problem
in that we are setting the quantity to load.switch orders and triggering the checkboxes wrongly

To test:
 1 - Create a new basket, create items on placing the order
 2 - Create an order line with 4 items
 3 - Create another order line with 2 items
 4 - Close the basket
 5 - Receive shipment and create an invoice
 6 - Select both orders via the checkboxes got multi-receive
 7 - Click "receive selected"
 8 - Edit first order line, quantity received = 1 (1 out of 4)
 9 - Verify that one item is also selected in the table
10 - Switch to "next order"
11 - Quantity received is 0, no items checked in the second order
12 - Switch to "Previous order"
13 - ERROR: Item checkbox was lost, quantity received still correct
14 - Switch to next order
15 - ERROR: item is now checked, quantity received 0
16 - Note: We see a mix up of the information entered, one has the checkbox now, the other the quantity.
17 - Save changes
18 - Click confirm
19 - Continue (complaint about the second order left unchanged)
20 - You are back on the summary:
     * pending order: quantity changed from 4 to 3 - correct
     * received order: quantity shows 1 - correct
21 - Click on receive for your updated order line (with 3 items)
     * 4 items show to be received (should be 3)
22 - Apply patch
23 - Cancel receipt of items
24 - Repeat 1-12
25 - Items are loaded correctly
26 - Try with various checkboxes and switch back and forth
27 - Confirm that manually adjusting quantity received checks the first n boxes
28 - Confirm setting quantity to 0 unchecks the boxes
