VCR acc test fixes

[slevenick]

Even more test fixes!

Getting a service account via getTestServiceAccountFromEnv skips the test depending on environment variables set. If this happens after we use a VCR-seeded random function (randString, etc) the test will attempt to read the seed file which never gets written because the test never passed. Putting getTestServiceAccountFromEnv first causes the tests to skip correctly
