> Currently the RMCommunicator will set the tracking url during unregistration once a job
has finished, regardless of whether it actually wrote history or not. If the write to history
failed for whatever reason, we should leave the tracking url as null so that we get redirected
to the AHS instead of getting a job not found on the JHS.
