Added some unit tests for koenig located in the /lib/koenig/test-support directory.

- `fileStorage: false` config is going away, it predates storage engines and will simplify future image optimisation work
- simplifies UI, it can be brought back in the future in a more robust fashion if required
no issue
- I was a little overzealous with the file cleanup, not realising that the template compiler must be specified even if it's not installed within the addon
no issue
- removes local addon dependency files to avoid confusion now that the host app manages dependencies
- removes unused tests directory
- these files may come back eventually, there's an open ember-cli RFC to improve in-repo-addon isolation and testing https://github.com/ember-cli/rfcs/pull/60
no issue
- as a separate project a number of Ghost-Admin components and files had been copied verbatim, these are no longer needed as the original components are available now that the editor is integrated
no issue
- this prevents the need for running `npm/yarn install` inside the `lib/gh-koenig` directory
- `ember-cli` may eventually be able to handle this with an `ember install` or similar command, there's [an in-repo-addon RFC](638cad2405/active/0000-better-in-repo-addons.md) suggesting this improvement but it hasn't got much traction yet - it may be necessary to wait until ember-cli has standardised on `yarn`
