Nested component import is wrong

When generating a component with a test, the `pathCase` method from `change-case` results in something like `my/new-component` being created with the import `"app/components/my/new/component"`.

**What I Expected**
```ts
import MyNewComponent from 'app/components/my/new-component';
```

**What I Saw**
```ts
import MyNewComponent from 'app/components/my/new/component';
```
