Test case ""scheduler" fails

[mountaindude]

Running npm test scheduler fails the last test case:

 H8: GET /v4/schedules/status
    ✓ It should respond with 200 when getting status (7 ms)
    ✕ Response should be a string (7 ms)

The Butler log does not show any warnings or errors.

This API endpoint returns text/plain rather than the application/json that most other endpoints return.
This is correct (for now), the test case however incorrectly assumes the response to be an object.
