fix(hapi-engine): schematics compatible with IIS Node and Azure App service

The problem is that the `interceptor.js` which is used by IIS Node will require the application files rather than executing it. https://github.com/tjanczuk/iisnode/blob/8657944f8803d84514c0c7ddd48c046aa68e6edf/src/scripts/interceptor.js#L210

Thus, the server `run` method will never get invoked.

Closes #1447
