write_fragment should return content when caching is disabled

     def write_fragment(key, content, options = nil)
         return unless cache_configured?

         key = fragment_cache_key(key)

         self.class.benchmark "Cached fragment miss: #{key}" do
           cache_store.write(key, content, options)
         end

         content
      end

line 2 should be return content unless cache_configured? Otherwise something like this render :json => write_fragment(key, some json data) will receive a nil value for render and look for an action.json.erb file instead of returning the non-cached value of content
