* Rename `wait` to `settled`
* Ensure existing `import wait from 'ember-test-helpers/wait'` code works properly
* Export `settled` as public API from the main `index.js`
* Move existing `wait` tests into `legacy-0-6-x` folder
Primary reasoning for the rename from `wait` to `settled`:
```js
test('can do xyz', async function(assert) {
await this.render(hbs`{{some-thing}}`);
await click('.some-thing');
await wait(); // <- WAT?!?!!?
});
```
This looks much better:
```js
test('can do xyz', async function(assert) {
await this.render(hbs`{{some-thing}}`);
await click('.some-thing');
await settled();
});
