The environment request controller can only check status of a single environment provider

[t-persson]

Description

We only create a single environment provider for each environmentrequest. In the future we may want to be able to run several at the same time. We should update so that we can at least check the status of all environment provider jobs that we have active instead of hard-coding index 0.
