[FIX] crm_iap_lead, crm_iap_lead_enrich: Uninstalling CRM

Steps to reproduce the bug:

- Let's consider an instance with crm_iap_lead and crm_iap_lead_enrich installed
- Uninstall crm

Bug:

An error was raised: ('Record does not exist or has been deleted.\n(Record: ir.model.fields(15085,), User: 1)', None)
because the field reveal_id is shared on model crm.lead and modules crm_iap_lead and crm_iap_lead_enrich are independent
from each other.

Inspired from https://github.com/odoo/odoo/commit/ff7efbb1e81cd6987601c03f0b75a37d2df8e331
