bigquery.it.ITBigQueryTest: testStatelessQueries failed

Note: #3492 was also for this test, but it was closed more than 10 days ago. So, I didn't mark it flaky.

commit: fa02595
buildURL: Build Status, Sponge
status: failed

From the logs, we don't expect the assertion to fail:
assertNotNull(tableResult.getQueryId());
Going to wait for the next test run to see if it's a more persistent failure.

Test passed for commit acea61c (Build Status, Sponge)! Closing this issue.
