[FIX] models.py: tree instead of list

Oversight in odoo/odoo#100376

The web client sends `list` rather than `tree` when requesting
views.

However, once they went through `get_views`, they are converted back
to `tree`.
https://github.com/odoo/odoo/blob/master/odoo/models.py#L1653

So, here, we should check against `tree`, not `list`.

Could be seen in Lunch > Manager > Today's Order.
With the `id` field missing, an error is raised
```
Uncaught (in promise) Error: The following error occurred in onWillStart: "field is undefined"
```
