Title: js-file.js: setting default tree to empty object

This allows an empty tree to be passed into the JsFile constructor from string-checker.js. Otherwise, if there's a parse error and tree is undefined, this throws an error in js-file.js:

```
return this._tree.comments;
```

This fixes the travis-ci build failure.
