removed some refs to fxaccounts domains that don't exist

@jbonacci I made this better, but if you grep through the code, you'll still find some hits to the said non-existent domains. I've removed those references from the visible README (they're commented out) and the logs, and turned off the certifier for now. I could change the domains to PLEASECHANGEMELATER.com if that is any better, but I suggest we just leave it for now until we get more visibility.
