Accounts with Admin customer group and "Super Administrator" role have no permission for accessing pages like "Own Error Pages" or "Redirect rules".

Steps to reproduce

1. install the shop
2. create a new customer
3. assign the customer group "Admin" to the new customer
4. go to Customers > Role and Permissions and assign the Super Administrator role to the new Admin account
5. logout
6. login with the new account
7. go to the Gambio Admin

Expected
The menu item Toolbox > "Redirect rules" and Contents > "Own Error Pages" exists and is accessable.

Actual
The menu items Toolbox > "Redirect rules" and Contents > "Own Error Pages" are missing and these pages are not accessable. Also it is not possible to edit customer groups.
