Previously, if a non-admin controller did not have a template defined, then the resolver would return an admin template with the same name. This is not the desired behavior, and regressed in fc36ac6cde. However, we *do* want this behavior for components defined in the admin bundle (because admin components are not namespaced).
This was noticed because the non-admin `badges` route was using the `admin/badges` template
This commit fixes the behavior, and adds a tests for these cases.
The default Ember resolver implementation allows this for components. We need the same for connectors (which are essentially components behind-the-scenes)
This switches us to use the modern ember resolver package, and re-implements a number of our custom resolution rules within it. The legacy resolver remains for now, and is used as a fallback if the modern resolver is unable to resolve a package. When this happens, a warning will be printed to the console.

Using arrow functions changes `this` context, which is undesired in tests, e.g. it makes it impossible to setup things like pretender (`this.server`) in `beforeEach` hooks.
Ember guides always use classic functions in examples (e.g. https://guides.emberjs.com/release/testing/test-types/), and that's what it uses in its own test suite, as do various addons and ember apps.
It was also already used in Discourse where `this` was required. Moving forward, it will be needed in more places as we migrate toward ember-cli.
(I might later add a custom rule to eslint-discourse-ember to enforce this)
We used many global functions to handle tests when they should be
imported like other libraries in our application. This also gets us
closer to the way Ember CLI prefers our tests to be laid out.
This is where they should be as far as ember is concerned. Note this is
a huge commit and we should be really careful everything continues to
work properly.
