Item10906: Checking other than USERSWEB ??

If a username is entered into a group in a way that might cause it to be
interpreted as a Web.Topic name,  TopicUserMapper ends up with a bogus
webname when doing auth checking.  For the TopicUserMapping contrib,
user topics can't be anywhere but in the Users web - so force that name
in as the web name.
