[YW] Deleting a universe with a released node requires "force delete"

Repro steps:

1. Create a 3 node YW cloud universe (tested against GCP)
2. Go to the nodes page at http://portal.dev.yugabyte.com/universes/e78b9592-0f2b-4e41-80e4-f30c94611b5b/nodes or equiv
3. Pick one node, "Stop Processes"
4. Pick same node, "Release Instance"
5. Destroy/delete universe. Do not check "force delete" Universe deletion fails.

If "force delete" is set to true, universe deletion succeeds, so this is not a high pri issue. However, setting force delete can mask other errors, so it would be good to eventually fix this.
