* 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.
