[AC-6482] Memory leak on list view, with huge dataset [Android]

Replication Step: 1. Created a new sample app 2. Updated the index.js as

function doClick(e) {
	var win = Ti.UI.createWindow({
		backgroundColor: 'red',
		fullscreen: true
	});
	var listView = Ti.UI.createListView();
	var section = Ti.UI.createListSection();
	var sectionData = [];

	for (var k = 0; k < 1000; k++) {
		sectionData.push({
			properties: {
				title: 'Row ' + (k + 1)
			}
		});
	}
	section.setItems(sectionData);
	listView.sections = [section];
	win.add(listView);
	win.open();
}

$.index.open();

If we open this app and profile the memory, you'll see there is a small memory loss each time, we click the list view. But in the code, if you change 1000 to 50000 (Which is our case where we have to show ~50000 items in the dropdown/list view), you can see significant memory leaks.
