Namespace deletion is not monitored

[rascasoft]

If you want to monitor a namespace that does not exists, vessel starts correctly anyways and once you start creating new resources, it correctly detects them:

12/29/2021 04:27:28 [watch_ha][INFO] -> mynamespace::Deployment::nginx-deployment
12/29/2021 04:27:28 [loggers][INFO] Handler 'on_event' succeeded.
12/29/2021 04:27:30 [watch_ha][INFO] -> mynamespace::Deployment::nginx-deployment
12/29/2021 04:27:30 [loggers][INFO] Handler 'on_event' succeeded.

And you get the results of the scan inside the database, so you can query and see them correclty.
Problem comes when you delete the namespace (and not the single resource, which works): change is not detected and you still get the issues inside the queries, even if the resource(s) does not exists anymore.
