fix: add dataset id in function call

[HemangChothani]

Fixes #43

[plamut]

Was there a test that failed because of that? If not, I suggest adding one that covers this code path to protect us from future regressions.

The fix itself looks good.

@plamut We are using test_create_scheduled_query.py file for testing, but this is call is from main function and use argument parser like for quickstart.py test

python-bigquery-datatransfer/samples/snippets/quickstart.py

Lines 40 to 41 in afe5219

	if __name__ == '__main__':
	run_quickstart()

not sure how to cover this kind of call and also not found for the quickstart as well.

@HemangChothani OK, fair enough, let's merge it then. 👍
