#17230
Fix for the following scenarios:
- Team has only one policy with calendar enabled. Events are created on
user calendars. Then the user disables the calendar on such policy.
Expected behavior: Events on the user calendar should be cleaned up in
that scenario.
- Policy `platform` is edited (which removes `policy_membership`
entries) and we'd like to have the calendar event removed for the hosts
that do not apply anymore.
To cover these scenarios I changed `ds.GetTeamHostsPolicyMemberships` so
that it also returns hosts that have a calendar event AND have no
results on policies (returned as passing=1).
E.g. this could happen if there ARE calendar events for a team but with
a platform that doesn't match the host (so it has no results).
