[FIX] crm,hr_recruitment: highlight and show others

When clicking on stat button "Meetings" on a partner, just highlight the
partner meetings as is done for similar stat button instead of having
a domain that hides other event (so when creating meeting, we can take
into account other existing meetings).

A similar change with same reasoning has been done for "Meetings" stat
button of hr.applicant records.
