[FIX] stock: decrease initial demand quantity

- Open a picking (example WH/IN/00002)
- Unlock
- Edit Initial Demand (from 35 to 4 for example)
- Click on Save

An error occurs: 'Record does not exist or has been deleted.'

When saving, the following values are sent to the server (example):
`{'move_ids_without_package': [
     [1, 31, {'product_uom_qty': 4, 'date_expected': '2018-10-02 08:27:14'}]
 ],
 'move_line_ids_without_package': [
     [1, 26, {'package_id': False, 'result_package_id': False, 'owner_id': False, 'lot_id': False}]
 ]}`

The field `move_ids_without_package` contains the new quantity. However,
decreasing the quantity will remove the reservation and therefore unlink
the move lines.

This means that the field `move_line_ids_without_package` refers to IDs
which have been deleted when writing on `move_ids_without_package`.

We can make the field read-only if it is not displayed.
