[FIX] base: fix domain of serialization_field_id in ir model field view

During refactoring of the field view, parent.model has been replaced by
model_id since it is more elegant. (odoo/odoo@4a60a3)

That was correct when you was working directly from the ir.model.field.
But if you was comming from ir.model -> fields -> 'add an item', the
model_id is unknow in the context of pyeval.

This commit close #12455
