Bug 1579168 - Fix updating metadata for results that are expected but have known intermittents, r=maja_zf We were assuming that in the case that the status matched expected we'd have no expected entry in the log data. But actually it was being set to None, so handle both those cases. Differential Revision: https://phabricator.services.mozilla.com/D44874
