Fix for the broken links on members page
Thx
We should rather use "id" because it is hardcoded in the persistence module.
- Now getGroup strips off the softwerkskammer suffix from the group name if present. 
- Adapted the function names (copy&paste relic).
Now getSubscribedListsForUser returns a Group object instead of a sympa result object.
