FixBUG mongoid

Hi , 

With mongoid 4.0.0 , rails 4.1.8, i've a problem with "with_role" method.
In code "role_table_name" is used , but for mongoid with namespace it don't work..
In my case i've "Organization::Security::Role" classe name and when the method is called ,it use tableize  but it's wrong..
I've changed role_table_name by role_cname.

In mongoid adapter , i've changed the "where" into "in", in my case mongoid raise an query error for resource_type wiht where but not with in method
