Fix SQL query to return 10 rows & simplify

[PicardParis]

• Original query returned a single nested row (instead of 10 rows as apparently expected in section print_results)
• Standard SQL specified directly in query
• Removed parameter max_results to avoid redundancy w/ query

Thanks.

@tswast @PicardParis This caused the system tests to fail. Can one of you send a PR to update the tests?

[PicardParis]

Proposed change still gets a PASSED:
simple_app_test.py::test_query_shakespeare PASSED

Failures are related to 2 other tests.
I think I see why. Let me check...

[PicardParis]

The 2 failures are in fact due to random queries in async_query_test.py and sync_query_test.py.

Proposed fixes in PRs:
#1043
#1044
