GZoltar includes tests that are not failing in failing tests

Sometimes, GZoltar includes tests that are passing in the failing tests list:

Example cm5:

Actual failing test cases:

org.apache.commons.math.util.MathUtilsTest#testGcd_1 FAIL
org.apache.commons.math.util.MathUtilsTest#testGcd_2 FAIL
org.apache.commons.math.util.MathUtilsTest#testGcd_3 FAIL
org.apache.commons.math.util.MathUtilsTest#testGcd_4 FAIL

The same can be observed in other examples. This results in non-suspicious lines being included in the suspicious set, as well as "fuzzing" the suspiciousness values.
