[FIX] hr_gamification: grant badge to employee of another company

This is a side-effect of commit [1].

Consider we have access to companies A and B, and current active company
is A. Before the mentioned commit we were able to grand a badge to an
employee in company B. We should keep that behavior, as long as the
current user have also access to company B.
