Fix Avatar upload on add new user
Fix Avatar upload on add new user

When specifying an Avatar via the 'add user' dashboard interface for new users, would fail with 'call to member function on non-object' for updateUserAvatar function. Calling the concrete/avatar helper before the call rectifies the problem. Maybe this makes the call setting the $av variable in the on_start function redundant? Left in there for now. All seems to work the way i've set it now (matching the 'edit user' controller's add/update avatar method, basically).
