When 757a455dde refactored the zones to go
from a list to a map, this broke the tests/common/resolver helper.
reproduction:
```
let
pkgs = import <nixpkgs> {};
testConfig = {
name = "resolver-repro";
nodes = {
acme = { nodes, ... }: {
imports = [ (pkgs.path + /nixos/tests/common/acme/server) ];
};
};
testScript = ''
'';
};
in pkgs.nixosTest testConfig
```
