A few weeks ago the Google Cloud Functions implementation that I worked on was merged with tests that were never run. This was reported by @martijnwalraven here.

I've created this issue which moves tests to their correct location and fixes some edge cases that were caught by the integration test suite when actually run.

@martijnwalraven I've included your changes here, I hope you don't mind.

TODO:

• Update CHANGELOG.md with your change (include reference to issue & this PR)
• Make sure all of the significant new logic is covered by tests
• Rebase your changes on master so that they can be merged easily
• Make sure all tests and linter rules pass
