Make sure we wait longer for new clusters (#208)

Created by: garloff

There was logic to ensure we wait longer for new clusters, as the control plane we wait does not even exist if we check too early, so the script may error out. Unfortunately, the logic was reversed, which is fixed now.

Should be backported to 3.x and 3.0.x after more testing.
