[NI] Relax rules for call completion: require at least one constraint
It's enough to have at least one good constraint. Note that the whole algorithm can be a bit more general: we could check also Out<T>, In<T> and verify that T has good only lower constraint or upper constraint, but there are questions for types like Inv<Out<T>>, where T should have lower and upper constraints #KT-31514 Fixed
