fix: Ensure Wait function waits for pods to appare in given namespace (…

…#803)

When the Wait function is called to wait for e.g. the expected outcome of another operator,
the operator might take longer then the initial interval time of 2s to create a pod.
In this scenario the Wait function would get 0 Pods returned from the API Server to check
the state of and assume all is done.

Ensure we at least get a pod count higher then 0 before we return successful. This gives
the other operator our 5min deadline to create and start the pod(s).
