Cannot send confirmation email if there is no 'User' model

[ybian]

TestCase:

1. Setup ng-token-auth and devise_token_auth_demo properly and make it work correctly;
2. Change the model name User to Developer and change routes.rb accordingly to:
   mount_devise_token_auth_for 'Developer', at: '/auth'
3. Test again with registration.

Expected Result:

Should send out confirmation email successfully

Actual Result:

Got the following exception:

ameError (uninitialized constant DeviseTokenAuth::RegistrationsController::User):
  /Users/ybian/.rbenv/versions/2.1.3/lib/ruby/gems/2.1.0/bundler/gems/devise_token_auth-2d3595d405b7/app/controllers/devise_token_auth/registrations_controller.rb:24:in `create'

Seems that there is hard-coded reference to User in L24 of registrations_controller.rb:

        User.skip_callback("create", :after, :send_on_create_confirmation_instructions)

Good catch! Thanks @ybian!
