fix: Fixed http-auth not honouring http_auth_guest (#6699)

Browse Source 
* fix: Fixed http-auth not honouring http_auth_guest

* Always fall back to http_auth_guest.
Make sure $username is set, otherwise, we won't try to authenticate.

* reverted elseif to default to http-auth-guest

* Update authenticate.inc.php

simplify logic
