Finished prebuild does not switch to "available" after execution is finished (stuck in "running")

Note: self-hosted installation

Not sure what's the cause here: UI bug, or status update gone wrong.

We had a chat with the user: in this case we have a bug in the state mapping (instance => prebuild): Snapshots could not be stored (because minio was out of disk space), and an instance update of {"status": 6, "snapshots": ""} did not results in a system failure (state: "failed" + "error")
