Fixes crash if the process we're wrapping uses process.send().
Essentially, what can happen is that the wrapped process uses process.send() for a test hook or a way to talk to a cluster master, and babel-watch will just happily try to pull filename off whatever object was sent and pass it to path. This can lead to a nasty error as path will refuse to resolve undefined.
