We have this check because in CI it is likely a single commit repo means a misconfigured CI job.
In the addon, this is much less likely, so we may as well allow you to run such builds as part of experimenting with a new storybook. I didn't add it as a CLI flag as it seems like asking for trouble.
I'm not sure if there's a good way to write tests for this. The original PR that added the check didn't have tests for #207 -- do you have any ideas @ghengeveld ?
