[ews] re-run-layout-tests ignores the failures when first layout test run failed with infra issue. eg.: https://ews-build.webkit.org/#/builders/10/builds/168571, https://ews-build.webkit.org/#/builders/10/builds/168925, https://ews-build.webkit.org/#/builders/10/builds/169015 In these runs first layout-tests failed and didn't even run layout-tests, re-run-layout-tests noticed some failures and compared with first run and thought them to be flaky and so ignored them. re-run-layout-tests shouldn't ignore the failures (as flaky) when first layout test run failed with infra issue.
