[FIX] web: allow updating a newly created kanban record

When using quick create to create a kanban record, if this record was
then updated thanks to a field widget, the view crashed. This was
because it tried to update the whole column but the newly created
record was not properly attached to it in the model.

Thanks to @sja-odoo for the test.

Note: to backport (partially)
