[Ingest] Zookeeper ingest status is incorrect

[mreyescdl]

While processing a 270 object UCJEPS batch there was a single failure due to an odd state issue.

org.cdlib.mrt.zk.MerrittStateError: State change (Downloading->Provisioning) is not allowed
        at org.cdlib.mrt.zk.QueueItem.setStatus(QueueItem.java:255)
        at org.cdlib.mrt.zk.QueueItem.setStatus(QueueItem.java:245)
        at org.cdlib.mrt.ingest.consumer.EstimateConsumeData.run(EstimateConsumer.java:579)

The Estimate consumer daemon thought it was in a "Downloading" state when it was "Estimating"
I'm not sure if this is a ZK library issue or a client one.

Code segment is shown below

            if (jobState.getJobStatus() == JobStatusEnum.COMPLETED) {
                if (DEBUG) System.out.println("[item]: EstimateConsumer Daemon COMPLETED queue data:" + jp.toString() + " --- " + ji.toString());
                job.setStatus(zooKeeper, org.cdlib.mrt.zk.JobState.Provisioning);
