[FIX] web: fetch specialData of fields in x2many form

Suppose that there is a one2many list in a form view containing
a field F, displayed with no widget, and that F is also displayed
in the one2many form view (opened when clicking on a record of the
list), but that in this form view, F is displayed with a widget
requiring specialData (additional data to fetch alongside the
record), e.g. widget="domain".

Before this rev., it crashed when this happened because those
specialData weren't loaded when opening the related record.

Credit goes to @pga-odoo for reporting the bug and reproducing it
in a test.
