New version : 16.0.1.0.3
_mark_done() only set partner_id/email when it created a *new* res.partner.
If the answer already had a partner_id/email (e.g. inherited from the Odoo
user logged in when the /survey/start link was opened), that value was kept
even though the record creation matched or created a different, correct
contact from the participant's own answers.
Now we always sync partner_id/email to the res.partner actually matched or created
from the participant's answers.
Add a migration to relink partner_id/email on existing done submissions.
