On EWS, tester queue should re-build when then fail to download built product. Currently they fail the build (e.g.: https://ews-build.webkit.org/#/builders/68/builds/6262). We store the build for ~14 days on amazon S3. If someone presses 'Retry failed build' button on Bugzilla after this duration, and a tester build is retried, it usually fails since it can't find already built archive. In such cases, instead of failing, we should re-build (either by re-building on tester queue or re-trigering corresponding builder queue).
