Undelegated test cannot be run

[matsduf]

Trying an undelegated test with version v2022.1 fails:

$ zonemaster-cli --version
CLI version:    v4.0.0
Engine version: v4.5.0

(...)
$ zonemaster-cli --ns nsa.dnsnode.net --ns nsu.dnsnode.net --ns nsp.dnsnode.net iis.se 
Seconds Level     Testcase       Message

The error can also be seen through GUI: https://zonemaster.net/result/7c0bc2376ff5070d

Running the command with previous release works as expected:

$ zonemaster-cli --version
CLI version:    v3.2.0
