The command "gulp watch" does not appear to work as of de-13.

Steps to reproduce

1. Install the theme generator.
2. Create a test theme - "yo liferay-theme".
3. Download the Porygon theme from the Marketplace and copy its source code into your test theme's src folder.
4. Install de-13 or de-14 and start the app server.
5. Run "gulp watch" from the test theme's project directory.

Expected Result: The theme builds and is deployed to the app server.
Actual Results: The theme builds but the bundle never starts and is never deployed. An exception is thrown in the logs.
