[FIX] stock_barcode_mrp: register by product to post-prod in 3 steps manufacturing

Enterprise17.0stock_barcode_mrpMedium

This update resolves an issue where multi-step production processes involving by-products weren't correctly creating manufacturing lines in Odoo. The fix ensures that by-product lines are properly generated when scanning final products and by-products during the barcode manufacturing process, streamlining production workflows. This issue is now resolved in version 18.0 and later.

Original PR description

### Steps to reproduce:

- In the settings enable By-Products an Multi-step routes
- Put your warehouse in manufacturing in 3 steps
- Create two storable products:
    - Final Product (FP) with an empty bom
    - By Product (BP)
- Go to the barcode app > Operations > Manufacturing > New
- Scan FP > Register By-Products
- Scan BP
#### > The line is created with pre-prod as location and prod as destination

### Cause of the issue:

Since no existing line refers to the by product, a new line is created and its `location_id` and `location_dest_id` are provided by the `_getNewLineDefaultValues`:

### Note:

The issue is no longer reproducible in 18.0+ as this change has already been applied in 2d5dbb93e6b33c2be786f9b2361c993f715d1a7f
