As of https://github.com/odoo/odoo/pull/114024, `display_name` is
implicit in every form view (see the use of addFieldDependencies in the
Form controller). Therefore, when you create a new record for this
model, it calls the first `onchange`, which will compute display_name
for a new record (id without origin). Some `_compute_display_name` don't
handle new records correctly and raise a traceback. These models are
sometimes directly accessible:
- Accounting > Account Group > New => Traceback
- Contact > Contact Tags > New => Traceback
Other models are inaccessible by default (no view to access or create a
new record), but if someone creates a view for them with studio (or
modifies an existing one to allow creation):
- `crm.iap.lead.role`
- `crm.iap.lead.seniority`
- `chatbot.script.answer`
- `payment.token`
Change the code of `_compute_display_name` on these models to be more
defensive and avoid (potential) tracebacks. Similarly, change the
`convert_to_display_name` of `fields.Datetime` to take into account
`None` value.
