[FIX] crm: opportunity meetings filters are set based on id

Steps to reproduce:
- install crm
- go to crm > configuration > settings > activate leads
- go to a contact > click the "opportunity" smart button >
create an opportunity > select the newly created opportunity > click
the "meetings" smart button

Previous behavior:
meetings are filtered with 'search_default_opportunity_id' set to active_id.
active_id is referring to the partner_id in this case. this leads to
a cache miss error.

Current behavior:
meetings are filtered by the right opportunity (current id).
