[BUG] [Critical] Access Tab For Cases should only be accessible to administrator user. Administrator can be locked out

[cyb3rmeerk4t]

Describe the bug The Access Tab when viewing a case for a standard user (non-admin user) can cause anyone, including administrator users to not be able to access the case.

To Reproduce Steps to reproduce the behavior:

1. Go to Manager Case > Select a Case
2. Click on Access tab
3. Other users can be denied and totally locked out to the case.

TestCase002 not accessible to administrator anymore:

And no way to see and get access to the said case. This works with other users as well. Only the user that set "denyall" access can revert the setting to full access.

Expected behavior A clear and concise description of what you expected to happen.
