Handle null SCA results in PredicateTest

Add guards in PredicateTest to skip scans with null results and to assume SCA result data exists before accessing it. These checks prevent NPEs and make the test resilient when scans or SCA payloads are missing, causing the test to be skipped instead of failing.
