Amjad Masad 477360b8c9 [react-packager] Make it safe to include files without a newline at the end
Summary:
@public
Fixes #1431
Fixes #1005
Files with no newlines and a comment at the end of the file would've caused a syntax error in the bundle:

```js
__d('module', function() {
hi();
// wow })
```

This fixes the issue by inserting a new lines before `})`.

Test Plan:
* ./runJestTests.sh
* ./runJestTests.sh PackagerIntegration
* open app to the playground app
* add an error
* observe that the redbox has the correct lines
