unsubscribe endpoint doesn't unsubscribe.

post to v1/sites/1/unsubscribe should unsubscribe the current user from the site if they are subscribed, but doesn't.

Hey @charlesx2013,

I've tried GET, PUT, PATCH, and POST, and get a 404 for each one.

this is the endpoint I'm hitting:
https://floating-bayou-8262.herokuapp.com/api/v1/sites/1/unsubscribe

I get "successfully subscribed to site!" from:
https://floating-bayou-8262.herokuapp.com/api/v1/sites/1/subscribe
with a POST.
