[ML] Updated filtering in DetectionRulesIt.testCondition() (#110628)

While working on elastic/ml-cpp#2677, I encountered a failure in the integration test DetectionRulesIt.testCondition(). It checks the number of return records. With the new change in ml-cpp the native code returns two more values that have no significant score. I added filtering those out in the integration test code so it continues working as expected.
