      * core: fix crash with no plugins

A Corefile that defines a zone without plugins crashes coredns with the
stack trace below. Change this to return a refused.

~~~ corefile
 example.org {
    whoami
    log
    cache
    debug
}

example.net {
}
~~~

Asking for anyhing in example.net does this. Add test that tests this.
