Title: Remove unused before_filter reference

I ran into an undefined method error... According to the authors [comment](http://blog.joshsoftware.com/2010/12/16/multiple-applications-with-devise-omniauth-and-single-sign-on/#comment-1957):

> save_referrer is a stagnant method and we can remove it now

So, this PR just removes the `before_filter` call.
