Breaks confusingly on reexported component classes

[ef4]

Before colocation, if someone had a component JS that is just a reexport of another component JS:

// app/components/one.js
export default class extends Component {}

// app/templates/components/one.hbs
One

// app/components/two.js
export { default} from './one';

// app/templates/components/two.hbs
Two

This actually gave you two distinct components with the different templates.

But after colocation, templates are associated with JS by value, and since:

import One from './components/one';
import Two from './components/two';
assert.strictEqual(One, Two); // passes

This means they can no longer have different templates. The codemod is unaware of this and just breaks your components.

A better output for the codemod would be rewriting re-exported component classes as extensions:

-export { default } from './one';
+import Component from './one';
+export default class extends Component {};
