[NI] Complete call if return type has proper lower or equal constraints

There was a silly bug: equal constraint is actually a lower and an upper
 constraint, but we checked only presence of lower constraints.

 Test is important as here we have one equal constraint and should
 complete inner call `foo<Int>()` without propagating it to `bar` to
 avoid using `NoInfer` annotation multiple times
