I suspect `list_rows` (`tabledata.list`) was being called directly due to no `page_size` parameter on `QueryJob.result` at the time.

The `is_dml` logic is not needed now that we moved to `getQueryResults` instead of `tabledata.list` (#375). Previously, the destination table of a DML query would return a non-null value that was unreadable or would return nonsense with DML (and some DDL) queries. Thank you for opening a Pull Request!
