Solved problem in AddRole2Group whithout having permissions

http://bugs.otrs.org/show_bug.cgi?id=8995

Without any of the permissiones being set, the script falsly informed that it had added the role to the group, but nothing happened.
Now any of the permissions MUST be set, or the script will report with an error and exits.

accidently removed a comment line and restored
Added comment for backward compatibility code.
