Kevin Ansfield 352c4af1d7 Refactored usage of .get('property') with es5 getters
no issue
- ran [es5-getter-ember-codemod](https://github.com/rondale-sc/es5-getter-ember-codemod)
- [es5 getters RFC](https://github.com/emberjs/rfcs/blob/master/text/0281-es5-getters.md)
- updates the majority of `object.get('property')` with `object.property` with exceptions:
  - `.get('nested.property')` - it's not possible to determine if this is relying on "safe" path chaining for when `nested` doesn't exist
  - `.get('config.x')` and `.get('settings.x')` - both our `config` and `settings` services are proxy objects which do not support es5 getters
- this PR is not exhaustive, there are still a number of places where `.get('service.foo')` and similar could be replaced but it gets us a long way there in a quick and automated fashion
