Steps to reproduce:
1. Create multiple plugin jails with the 'standard' setting. iocage will create multiple jails irssi_2, irssi_3, etc.
2. Create a jail with the 'advanced' WebUI setting. It will faill because of: https://jira.ixsystems.com/browse/NAS-101622
3. WebUI/Middleware will destroy the base jail (irssi) in the example above.
1. Don't destroy a jail you weren't manipulating.
2. Destroy a jail by the UUID and not by name.
