Test: caseNullWhenNullDoesNotMatch (line 201)

Cypher query to execute:

RETURN CASE null WHEN null THEN 'matched' ELSE 'not_matched' END AS result

Expected behavior:

CASE null WHEN null THEN 'matched' ELSE 'not_matched' END should return 'not_matched'

ArcadeDB result:

{"result": "matched"}

Neo4j result:

{"result": "not_matched"}

In a simple CASE expression, null should never equal null. The comparison null = null yields null, not true, so the ELSE branch should be taken.
