K2: add test for KT-56520, case (7), qualifier receivers (3)

This commit covers object vs static member case,
when no companion objects are in the scope.
K1 reports UNRESOLVED_REFERENCE here, probably due to ambiguity.
About K2, while resolving Some.foo it first tries to resolve Some
as a "general" variable access, and gets two erroneous candidates
without companions. After it tries to resolve Some as a qualifier,
but we have no scope with a single qualifier.
That's why we finally report NONE_APPLICABLE on candidates with companions.
