Issue Summary

When restricting a Team Calendar, any user with administrative permissions on Confluence will be able to access and edit the calendar, even though they're not listed in the calendar's restrictions.

Steps to Reproduce

1. Create a calendar;
2. Restrict it to a specific user or group (either edit or view restrictions)
3. Try to access/ edit the calendar using a Confluence admin user (not listed in the restrictions)

Expected Results

The calendar shouldn't be accessible / editable to that user;

Actual Results

The calendar is accessible / editable to the user as long as they have admin permissions in the space.

Workaround

Currently the only workaround is to make sure the user doesn't have the Administrative permissions on Confluence.
