[FIX] stock: print all barcodes when picking qty done is at 0

Steps to reproduce the bug:
- Go to Inventory > Transfers > Select a ready transfer with no qty done
- Print > barcodes (ZPL) or barcodes (PDF)

Problem:
The file is empty because there is no qty_done.

Solution:
If no qty is done, then print all barcodes as if picking is done.
It makes sense, for example, when a user wants to print the barcodes before the product is delivered

but if at least one move_line has a Qty_done then do not print the other move_lines which have a qty_done of 0
