Resolves #1682

[cpcloud]

@xmnlab I've put up #1738 to address the BigQuery auth issues.

[xmnlab]

awesome! thank you so much @cpcloud !

[cpcloud]

@xmnlab Can you rebase?

[xmnlab]

rebase done!

[cpcloud]

It looks like I didn't fix the auth stuff. I know why, putting up a PR.

[xmnlab]

@cpcloud thanks!

[cpcloud]

Ah actually there appear to be a few cases where I call ibis.bigquery.connect without checking for credentials first.

[cpcloud]

@xmnlab Can you cherry-pick from #1741 and see if that fixes the CI for you?

[xmnlab]

@cpcloud awesome! thanks I will do it!

[xmnlab]

I am trying your changes on #1683
