[ews] Do not consult results database for failures when test run exit early due to too many failures. For eg.: In https://ews-build.webkit.org/#/builders/73/builds/21798 re-run-layout-tests failed with "Exiting early after 60 failures", but we still consulted results database for each of those failures. That's isn't useful, because even if all those failures are pre-existing, we still can't mark the build as successful since test run was exited early (didn't run all the tests).
