Title: Allow users to unsubscribe from yanked gems.

I was subscribed to [mongomapper](https://rubygems.org/gems/mongomapper) but it got yanked as it changed name to [mongo_mapper](https://rubygems.org/gems/mongo_mapper). Now mongomapper is still in my subscriptions list, but when I click through, I can't unsubscribe.

This pull makes the unsubscribe link available on yanked gems you're subscribed to.
