cubicweb #3207676 "cubicweb-ctl upgrade" starts instance whereas it was not running before [done]

The option --nostartstop (don't try to stop instance before migration and to restart it after.) could be abused to by-pass this; but it seems to me that an instance should not be started if it was not running before upgrade.
