Tries to run tests on /collections/null?_fd=0&pb=0 if the store has no custom collections

[JasonHassold]

In the case where you have a store that only contains smart collections the lighthouse-ci-action will try to run tests on /collections/null?_fd=0&pb=0 since null is the response that it gets from collection_response="$(api_request "$host/admin/api/2021-04/custom_collections.json?published_status=published&limit=1")"

The request should probably instead be made to the /collections.json API route

The /collections.json route doesn't seem to exist. Unless I'm misreading our own docs 🙈

But we definitely could try to ping /smart_collections.json when the result is null.

Haha you are right that it isn't documented but I tried it and it seems to be working. I was originally going to recommend checking if it is null and then pinging /smart_collections.json as a backup, but then I just tried /collections.json (which imo makes sense as a route) and it returned a result. The docs should probably be updated to include this route since it seems to be a part of the API, but idk where to report that

Thanks for letting me know. I'll ping the docs team!
