Add a system test to call `fetchall()` when multiple rows are expected.
This error applies to all BigQuery iterators, not just DB-API.
It was allowed before, but it didn't result in the correct behavior.
In BigQuery it means the page size, but the HTTPIterator it meant "don't fetch any more pages once you have these many rows."
