Issue Summary

• Deleted user groups don't show up in the page restriction dialog.
• But still appear to lock the page, without the option to remove them individually.

Steps to Reproduce

1. Add a page view restriction to a page in Confluence, making sure to add a "user group" into the list of exemption.
2. Proceed to delete the "user group" from the site's user/groups management.

     3. Check on the Space's restriction list;

https://<SITE-NAME>.atlassian.net/wiki/pages/listpermissionpages.action?key=<SPACE_KEY>

The "user group" will no longer be visible/listed. 

    4. Remove the remaining restriction for the page from the restriction list

https://<SITE-NAME>.atlassian.net/wiki/pages/listpermissionpages.action?key=<SPACE_KEY>

    5. Check on the page and it will still be restricted

    6.Any Space admin: Check on the restriction list, and there'll be no pages listed 

Expected Results

• Deleted "User groups" should either:
  • Not apply to the page, or
  • If they apply, should be removable via the page restriction dialog.

Actual Results

• Deleted "User groups" continue to restricts pages
• And can't be directly cleared from the page restriction dialog.
