Fail a test that reaches the network - #232

Conversation
Importing the `tests` package now refuses the network to every test in it, so a test that makes a real request fails naming the address it tried to reach, rather than being answered by the live registry. `socket.getaddrinfo` refuses a request to a host name before its lookup reaches the resolver, and `socket.socket.connect` refuses one to a literal address. The refusal is a `RuntimeError` rather than a connection error, since `io.fetch` turns a `requests` exception into a logged `None` and would leave the run green. Closes #216.
