Deleting folders of groups or roles (security app) will always check for users having assigned a group OR a role with the name of the items in that folder. This might result in cases where one cannot delete a folder containing a group "foo" because there's also a role "foo" which is assigned to a user. Deleting a folder of groups should only check for users and groups having that group assigned (and not for those having assigned a role with that name) - likewise deleting a folder of roles should only check for users and groups having that role assigned (and not for those having assigned a group with that name).

to reproduce:

• open security app
• go to groups
• create a folder "untitled"
• create a group "group-or-role-name" within the above folder
• go to roles
• create a role "group-or-role-name" (doesn't matter whether this is on root or in a folder)
• go to users, select one (e.g. peter) and assign him the ROLE "group-or-role-name"
• go to groups, select the folder "untitled" and try to delete it

-> system will tell you, you cannot remove that folder because user peter users "group-or-role-name" but actually it only uses the so called role not the group and hence the deletion should be allowed!
