Fix waiting on StatefulSet scale down (#391)

Browse Source 
Fix waiting on StatefulSet scale down

SUMMARY

When scaling a StatefulSet down to 0 replicas the wait will fail
because some properties of the status (readyReplicas, updatedReplicas)
will not exist. These are probably defined as omitempty in the API and
since the value is zero are not present in the response.

Fixes #203
