What this PR does:
startAllNodes should only take into account nodes that are part of the desiredRackInformation. That way we don't start phantom nodes that were created by the StatefulSet controller are not supposed to be part of the Cassandra cluster itself.

This is what causes flakes with scale_down_unbalanced test.

Which issue(s) this PR fixes:
Fixes #744
