When having a shipper for a DO, if the user creates a backorder, the
information won't be sent to him.
To reproduce the issue:
(Use demo data)
1. Create a sale order SO with 2 products
2. Add Shipping: UPS US
3. Confirm SO
4. In the associated picking, deliver one of the products and create a
backorder
5. Process the backorder
Error: In the chatter, there is a label for the first picking but there
isn't any label for the backorder
When confirming the sale order, the backorder is first created and then
the initial picking is sent to UPS. As a result, considering the current
body of `send_to_shipper`, the field `carrier_tracking_ref` of both the
initial picking and the backorder is defined with the same value (i.e.,
the tracking number of the initial picking)
Therefore, when processing the backorder:

`carrier_tracking_ref` is already defined, so `send_to_shipper` won't be
called
