assertj refasters could fix up allMatch

[carterkozak]

I think using .isTrue() on any kind of complex assertion is probably a codesmell, so might be worth replacing stuff like this:

-assertThat(result.getTestResults().stream().allMatch(
-        testResult -> testResult.getType().equals(RegressionTestResultType.NO_REGRESSION))).isTrue();
+assertThat(result.getTestResults()).allMatch(
+        testResult -> testResult.getType().equals(RegressionTestResultType.NO_REGRESSION));
