Currently several ACL checks are performed against the "core.admin" (Configure) action for the Redirect Manager, which isn't correct. This patch fixes the wrong checks.

## Test instructions:
- Create a new user group "Test" with Public as Parent Group
- Go to the Global Configuration, tab permissions, and allow "Admin Login" for this group
- Go to Users -> Access Levels, open level "Special" and assign the group "Test" to the level
- Go to the Redirect manager, click on the Options button, open the permissions tab and allow these actions for the "Test" user group:
  - "Access Administration Interface" 
  - "Edit" 
  - "Edit State"
  - "Delete"
- Create test user, assign to Test group only
- Login with test user
- Confirm that you can't:
  - change the state of a redirect item
  - empty the items that are in the trash
  - select one or more item(s), and update the Destination URL by using the "Destination URL" feature at the bottom of the page
- apply patch
- Confirm that your test user now can:
  - change the state of a redirect item (Edit State)
  - empty the items that are in the trash (Delete)
  - select one or more item(s), and update the Destination URL by using the "Destination URL" feature at the bottom of the page (Edit)
- Change the permissions for the mentioned actions, and confirm you can or con't perform above actions depending the ACL setting.

Thank you for testing!
