Title: Correct job response key

Although this is the legacy library, this might be worth correcting.
The correct key to extract the failure reason using MutateJobService is 'failureReason' rather than "failure_reason". This was tested with v201406. Today is the official release of v201409, this could be corrected when the library is updated to that API version.
