Using key as reference to a service

[bedrosenator]

I'm not sure if it was supported properly, but it worked well before upgrade to 0.3.8

We used a service to store query params in application controller to be accessible within our application.
So it was was working code

export const appQueryParams = new QueryParams({
  'someService.property': {
      as: 'property',
      defaultValue: 3600,
      replace: true,
      deserialize(value) {
        return parseInt(value);
      }
    }, 
});

export default Controller.extend(appQueryParams.Mixin, {
  someService: Ember.inject.service(),
})

But now it works only in case of alias is being set in controller like this

export const appQueryParams = new QueryParams({
  someServicePropertyAlias: {
      as: 'property',
      defaultValue: 3600,
      replace: true,
      deserialize(value) {
        return parseInt(value);
      }
    }, 
});

export default Controller.extend(appQueryParams.Mixin, {
  someService: Ember.inject.service(),
  someServicePropertyAlias: alias('someService.propertyAlias'),
})

Is this functionality supported? Or maybe there are issues in our code?
Thanks for help
