NI: Fix callable references resolution when LHS is generic nested class

In case of null qualifier, we should not look into any static scope
NB: factory::createCallableProcessor returns NoExplicitReceiver processor
in case of null-receiver, that makes resolving the call in the test as
`property(::key)` that matches to the property itself, thus leading to
overload resolution ambiguity
