Getting labels of Datasets (BigQuery) using the getLabels() in DatasetInfo

[asuresh4]

I tried retrieving the labels I set on a Dataset through the UI and gcloud API using the getLabels() method in this class: https://github.com/GoogleCloudPlatform/google-cloud-java/blob/master/google-cloud-bigquery/src/main/java/com/google/cloud/bigquery/DatasetInfo.java. I always a null value. I tried filtering on the same labels using the gcloud API and that works. Could you please look into the issue. Thanks!
