Unable to create appointment in team calendar is moderator/member

Steps to reproduce

1. Create a team in Contacts (not a Group)
2. Create a team calendar
3. Go to calendar app with an account which is not the owner of the team (but e.g. moderator)
4. Try to create a new appointment in the team calendar

Expected behavior

It should be possible that every team member can create new appointments (or give the option if everyone or only owners or moderators can create new ones).

Actual behavior

Can only create an appointment as the owner of the team. As a moderator it is only possible to create an appointment in personal calendars, but not in team calendars.

Reproduce the moderator/member scenario in the Calendar app using a team calendar, then trace the permission check for appointment creation. Compare owner, moderator, and member behavior and look for existing permission or calendar-sharing tests. Done means the intended role policy is enforced and covered by a regression test.
