Testrun controller should be able to get status from multiple suite runner jobs

[t-persson]

Description

We only run a single suite runner per ETOS testrun. In the future we should probably start up one suite runner per sub suite instead and to make that work we should get status from every suite runner. Now we have hard-coded index 0 on the suite runner jobs.
