When I run `react-native start` or `npm start` the packager starts and prompts to be `Looking for JS files in /Users/map/repos/myrepo/`

I've got Hot reloading enabled. When I change a file located within `/Users/map/repos/myrepo/node_modules/react-native/` seems to detect the change, however if I edit a file in a third party repository like `/Users/map/repos/myrepo/node_modules/react-native-menu/` looks like watchman is not detecting the change.

I've just upgraded React Native in my project to 0.39 and I think this wasn't the default behavior before. I've set up some logging in `react-packager/src/node-haste/index.js` and seems `react-native-menu` files are included in `hasteFSFiles`, however `change` event is not triggered.

I've tried deleting `node_modules` and reinstalling it, Cleaning Watchman state and other without luck.
