IFP: Only format the output name to the short version before output
    
    The ifp_user_get_attr_done() request handler was reused for both
    GetUserGroups and GetUserAttrs requests. Yet, it performed output
    formatting of name and nameAlias.
    
    This is bad, because the output formatting should really be done only
    during output. Also, it broke any post-processing of the returned
    message which the request might do later.
