SafeCacheKey + Touch doesn't pass spec/integration/mongoid_spec.rb.

  1) Mongoid integration using Garner::Strategies::Binding::Key::SafeCacheKey with Garner::Strategies::Binding::Invalidation::Touch end-to-end caching and invalidation binding at the instance level binding via find does not invalidate results for other like-classed objects

A simple example where you bind on a model doesn't work either, the following code never hits the cache.

get do
   garner.bind(Widget) do
       Widget.all
   end
end
