Calendar restrictions not working as expected

Issue Summary

Calendar restrictions not working as expected when from Space Calendars(https://<site>/wiki/spaces/<spacekey>/calendars) >> Restriction. There are a few scenarios given below.

Steps to Reproduce

Create a Calendar using UserA

Scenario 1: If all added users are given view access, all users are able to edit the calendar.

1. Add restriction to the calendar with view access for UserA
2. Add another user UserB with view access to the restrictions of the calendar

Expected Results

Edit access should be restricted, at least for user B (considering UserA is calendar creator)

Actual Results

Both UserA and UserB are able to edit and add events to the calendar

Scenario 2: User can't view calendar even with edit restriction if any other user has view restriction to the calendar

1. Add restriction to the calendar with view access for UserA
2. Add another user UserB with view access to the restrictions of the calendar
3. Add another user UserC with edit access to the restrictions of the calendar

Expected Results

UserC should be able to edit the calendar since as per the bug CONFCLOUD-72691, we can't grant both view and edit permissions to the same user.

Actual Results

UserC is not able to see the calendar.

Workaround

Currently there is no known workaround for this behavior.
