This isn't a proper fix, because the following command still crashes:
box.schema.user.passwd(123)
And this one crashes too:
box.session.su('admin', function(x) return #x end, 123)
Making error messages user-friendly is good, but I think that #3659 is
about invalid usage of luaT_error in lbox_session_su...
