[FIX] web: fix edition of a reference field

How to reproduce
================
You must have
- a form view with a one2many list
- in this one2many list add a column of a reference field

How to reproduce
1. open the record associated to the reference field
2. edit this record in the form modal view
3. click on save
-> Traceback

Bug
===
In `basic_model` the attribute `localData` become inconsistent
because of the method `_fetchReferenceData`.

We want to store the ID of the parent and not the all dict.
