Removed corresponding binaries.

Removed all Bill of Materials demo data, that were ridiculous and replace them by 2 bom: A complete
computer, and a kit computer. Rewritten the tests accordingly.

Fixed tests :
- sale_mrp/test/cancellation_propagated.yml : The yaml ref function return a id, not a dictionnary
- sale_stock/tests/test_sale_stock.py : The service product invoiced on the delivered quantity was
  in fact not invoiced on delivery on the test. As we are in sale_stock, Without timesheet, we
  manually set the delivered qty for the product serv_del. If we don't do this, the invoice will
  never be fully invoiced.
- The pricelist rules choice is not based on the sequence anymore (Seems to be a bug, reported to
  online). By the way, I changed the product to avoid the overlap.
- sale_mrp/test/sale_mrp.yml: The yaml ref function return a id, not a dictionnary
- mrp : Rewritten the tests to be coherent with the new bom data
