Failing Test: refreshes expired credentials

[cat5inthecradle]

This test has been failing for an unknown amount of time.

https://github.com/code-dot-org/aws-google/blob/main/test/aws/google_test.rb#L99

I'm not sure if this represents an actual issue, as no users have reported issues with daily usage. In #7 I propose we skip it until this issue is resolved.
