What this PR does / why we need it:
Today KCP produces confusing error messages if it can't scale up the control plane because one of the already existing Machines doesn't have a nodeRef (e.g. because it doesn't have a providerID). This PR improves the error log

Before:

"events: Waiting for control plane to pass preflight checks to continue reconciliation: [machine capi-quickstart-control-plane-5tgwz does not have APIServerPodHealthy condition, machine capi-quickstart-control-plane-5tgwz does not have ControllerManagerPodHealthy condition, machine capi-quickstart-control-plane-5tgwz does not have SchedulerPodHealthy condition, machine capi-quickstart-control-plane-5tgwz does not have EtcdPodHealthy condition, machine capi-quickstart-control-plane-5tgwz does not have EtcdMemberHealthy condition]",

After:

"events: Waiting for control plane to pass preflight checks to continue reconciliation: Machine capi-quickstart-control-plane-5tgwz does not have a corresponding Node yet (Machine.status.nodeRef not set)"
