Bring measurement SQL snippets up to date.

Update SQL to fix https://github.com/all-of-us/workbench-snippets/issues/19

Also:

• Rename BigQuery table prefix to disambiguate from Dataset Builder datasets.
• Fix a broken SQL unit test.
• Configure bigrquery to use a larger page size by default.

I ran the R smoke tests, the Python smoke tests, and the SQL unit tests.

• I used an override of .all_of_us_config.json so that the smoke tests ran against the newer CDR.
• Note that the Python setup snippet needs the pip upgrade command to take care of the plotnine vs. statsmodels incompatibility, but I'll send that in a separate PR.

Thanks for the review @calbach !

I think nearly everyone will be moving to the new CDR version. Let's keep this possible solution in mind for later, as you suggest.
