Title: fix constants name error with redis-rails & redis-store

和redis-rails或redis-store一起工作时会有问题
因为redis-rails中有Redis::Rails类，所以在Redis class下Rails其实是Redis::Rails，这样Rails::Railtie其实是Redis::Rails::Railtie，会报错NameError

redis-store在Redis下会有Redis::ActiveSupport类，所以同上ActiveSupport::Concern其实是Redis::ActiveSupport::Concern也会NameError

这两个gem用的还是很广的。。所以在这里fix吧
