PIPELINE: add testing for job controller and job state

[nielsboecker]

Update: Have been analysing some more and found the problem. It was actually that @ansonwong9695 you started a real job here:

def test_start_new_job():
    result_success, result_job_response = start_new_job(sample_job)

This job continued running, and in the course of subsequent tests, caused unexpected behaviour (due to the Accessor call not being mocked). The reason that only lung pipeline was affected is that the tests run in alphabetical order, and the other pipelines run before the jobs stuff. 💩

I will add a fix.
