If a task exits with exit code != 0, it appears as "completed" on taskcluster-inspector.

Commit pushed to master at https://github.com/taskcluster/taskcluster-worker https://github.com/taskcluster/taskcluster-worker/commit/48e1ce1f47f13be11f130d795d0d5c696b992f39 Bug 1303830: Report failed tasks correctly. Task management code erroneously was using the success boolean flag to check if the task has completed successfully, when we actually have to check resultSet.Success(). This led to failed tasks been reported as successful.
