Title: Make attributes class same as attrs in MultiParameterAttributes process_attributes

I wrote a fix for the problem I was having in this issue:
https://github.com/mongoid/mongoid/issues/2599
Now when calling super, the parameter `attributes` will be the same class as the parameter `attrs` in order to works with the `strong_parameters` gem.
