Errors produced when CTRL+X the text from the input field

Seems when you CUT the text out of the field it calls the API with a blank query
GET https://api.github.com/search/users?q= 422

Which then causes a bunch of errors

I fixed this by checking length in the lookup method:

if (this.query.length < 3) {
    return;
}

Also short queries will be also ignored, so it won't spam server.
