[Misc] Jenkins is now failing the build on some errors reported by Jasmine. These errors have been there for a long time but previously it seems Jenkins wasn't checking the log output. Silence those for now. If a jasmine test fails, the build will stop anyway. We might want to direct the logs to an output file iun target/ instead in the future.
