Scopes don't work with subclasses

[jafuentest]

Steps to reproduce:

Define the following classes:

class Transport
  include Mongoid::Document
  include MongoidEnumerable

  enumerable :terrain, %w[land water]
end

class Car < Transport; end

class Boat < Transport; end

Now, running:

Car.all gives the following criteria

 => #<Mongoid::Criteria
  selector: {}
  options:  {}
  class:    Car
  embedded: false>

Car.land gives the following criteria

 => #<Mongoid::Criteria
  selector: {"terrain"=>"land"}
  options:  {}
  class:    Transport
  embedded: false>

Notice how Car.land sets the selector {"terrain"=>"land"} correctly, but sets the class to the superclass Transport, so Car.land will give you all Vehicles of land terrain instead of just cars with land terrain

I'll try to see if I can fix it myself and send you a PR
