Fixed bug messing with error handlers when listenFD() is called instead of listen(). [thanks guillermo]
Fixed bug messing with error handlers when listenFD() is called instead of listen(). [thanks guillermo]

programs such as "spark" call listenFD() to call listen(1) with
a file descriptor, BUT Express was only proxying listen()
to register these handlers. Thanks for catching this bug guillermo!
