Parse Push - MaxListenersExceededWarning

[acudworth]

Issue Description

When sending push notifications from Parse server using the code below, I get node console error messages sent every 10 mins (see below). The push notification sends correctly.

Steps to reproduce

Send a Parse push via cloud code, e.g.:

        var pushQuery = new Parse.Query(Parse.Installation);
	pushQuery.equalTo("appIdentifier", "some.app.id");

	return Parse.Push.send({
	  where: pushQuery,
	  data: { 
	  	alert: 'test',
    	        badge: 1,
    	        sound: 'default'
	  }
	}, { useMasterKey: true });

Expected Results

No problem
