panic: cannot run experiment: no URLs returned

I'm not sure why this experiment was run, I invoked miniooni with web_connectivity - it looks like the vanilla tor test was run instead

This is still a web_connectivity run. The vanilla tor log was an fmt log hanging around. It only shows the response of the check-in API result. #1786 removes this. I suspect we did not receive any inputs to run the experiment which is why we see the panic. I am going to go ahead and close this issue.
