Fix second test in autocomplete-component

[algo74]

At least in my case, the test was falling because triggerKeyEvent(this.element.querySelector('.list-filter input'), "keyup", 83); apparently did not modify the value of the input field.

Works in the super rentals repo: https://github.com/ember-learn/super-rentals/blob/master/tests/integration/components/list-filter-test.js#L65

Maybe try that out and try to find the difference in what you are seeing.

In the repo, the line 68 is
assert.ok(this.element.querySelector('.city'), 'one result found');
if replaced with correct
assert.equal(this.element.querySelectorAll('.city').length, 1, 'One result returned');
the test fails.

My solution is probably not very good though. For instance, fillIn is introduced in the next test on this page.

it seems like the assert.ok would be ok, since I believe it gives back undefined if it can't find the selector. Will have to investigate though.

[algo74]

The test must assert that the component shows exactly one item. A query with empty string returns three items (it is tested in the first test).

You're right. Thanks @algo74 ❤️
