If we prepopulate the test homeserver with a key for a remote homeserver, we can make federation requests to it without having to stub out the authenticator. This has two advantages: * means that what we are testing is closer to reality (ie, we now have complete tests for the incoming-request-authorisation flow) * some tests require that other objects be signed by the remote server (eg, the event in `/send_join`), and doing that would require a whole separate set of mocking out. It's much simpler just to use real keys.
