Check checktest.py related errors shown by our network-health scanners
I often see something like
2020-03-17 21:03:56,973 modules.checktest [ERROR] Check thinks <https://metrics.torproject.org/rs.html#details/296B2178FD742AB35AB20C9ADF04D5DFD3D407EB> isn't Tor. Desc addr is 126.96.36.199 and check addr is 188.8.131.52.
. We should figure out a) what's up with that and b) whether we actually still need that test to be running.
