[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
