[FIX] account: editable export, traceback on "Tax Cash Basis Entry of"

Steps to reproduce the bug:
- Select an invoice in the list
- Click Action -> Export
- Select "I want to update data (import-compatible export)"
- Click the field "Tax Cash Basis Entry of"

Bug:
Traceback

Cause:
Crashes because of a KeyError here: https://github.com/odoo/odoo/blob/2d860cdddf29b9fbd1a5401082c9f743028d2fb5/addons/web/controllers/main.py#L1743
The KeyError occurs because AccountPartialReconcile hasn't got a `name` field; `rec_name` is therefore `None`. Setting it to any field fixes the issue and `id` is the safest.
