fix error handling in packager

Browse Source 
Summary: Currently on error I have following output:
```
 ERROR  Packager can't listen on port 8081
Most likely another process is already using this port
Run the following command to find out which process:

   lsof -n -i4TCP:8081

You can either shut down the other process:

   kill -9 <PID>

or run packager on different port.

See http://facebook.github.io/react-native/docs/troubleshooting.html
for common problems and solutions.
