When configuring CircleCI, the API token field is required, but this is only an aspect of the form field. We ended up running into some situations (particularly in unit testing) where the integration was configured but the API token was unset. In this case, we'd end up with bad requests. This change checks for an empty or missing API token, and preemptively fails the operation. The error will be logged as well as included in the status update. Testing Done: - Tested that attempting to start a request with a missing API token produced the correct log and error. - Ran unit tests.
