/projects/{projectId}/queries/{jobId} endpoint does not respect the maxResults query parameter

[ohaibbq]

What happened?

When requesting with ?maxResults=0, results are still included.

What did you expect to happen?

Query results should be limited to maxResults in the response

How can we reproduce it (as minimally and precisely as possible)?

POST /projects/{projectId}/jobs with a QueryJob
GET /project/{projectId}/jobs/{jobId}?maxResults=0

Anything else we need to know?

This raises an error in the Python BigQuery library when querying timestamps. The library doesn't expect data for this initial request so it doesn't send the formatOptions.useInt64Timestamp parameter. It sends the format option on subsequent paged requests.

client = bigquery.Client("...")
results = client.query("SELECT TIMESTAMP '0001-01-01 00:00:00.000000+00', TIMESTAMP '9999-12-31 23:59:59.999999+00'")
