[IMP] stock_barcodes: Avoid NewId environment calling method on_barco…

…de_scanned instead of onchange

Onchange limits documented in method:
It is not possible for a ``one2many`` or ``many2many`` field to modify
itself via onchange. This is a webclient limitation - see `#2693 <https://github.com/odoo/odoo/issues/2693>`_.

This causes refresh problems when creating or modifying records, and it is also not ideal to create records in "onchange mode"
