[TIMOB-6683] Android: modules: event listeners set on modules do not work

support event listeners on external modules In order to test, use the following app.js:

var harness = require("ti.harness");

harness.addEventListener("Test",function(e) {
	Ti.API.info("-----------> Received event for harness:" + e.Test);
});

harness.testEventKrollDict();
harness.testEventHashMap();

and then build the attached module. Once the module is built, include in the app and when run two messages should be seen for HashMap and KrollDict.
