zone is still available and being served after zone remove #393
Description
cascade 0.1.0-alpha5 built from source on AARCH64
I remove a zone only to find it's still being served.
$ cascade zone remove example.net
Removed zone example.netJust for laughs, because I wanted to see the NXDOMAIN, I continue:
