[FIX] stock: remove products not present in the package

Delivery slip packages contains products not present in the package

Steps to reproduce:
1. Install Sales and Inventory
2. Go to Settings > Inventory > Operations and enable Packages
3. Create and confirm a sale order with product A, B and C
4. Click on the delivery smart button and create and assign different packages for products A and B
5. Set done quantities for products A and B
6. Validate the delivery with no backorder
7. Click on Print > Delivery Slip
8. Product C is in both packages

Solution:
Don't print empty moves when packages are used

Problem:
`_get_aggregated_product_quantities` returns all move lines related to a certain `stock.picking`, even the empty ones
It is called for each package so the same empty lines will be displayed for all packages
