When the --debug-always flag is passed, we mark the cluster as saved to let the cluster destroy know not to destroy it.
Previously, we only marked a cluster as saved at the end of a test. However, if the caller terminated the test through ctrl c, which also destroys all clusters, it would lead to a race condition where sometimes the cluster would not be saved in time and get destroyed.
This change moves the cluster save to immediantly after the cluster is created.
