[TIMOB-7027] iOS: View - not all memory is released when a view is removed

When a view is removed from the window the proxy is being released as it should, but there is still memory that is not released. See screen shot of instruments.

Steps to repro:

Step 1: run the code below Step 2: have instruments monitoring the allocations of the app Step 3: click the window (views will be added to the window) Step 4: click the window again (those views will be removed from the window) Step 5: with the iOS Simulator selected click Hardware>Simulate Memory Warning Step 6: notice that the view proxies are released but there is still some memory left over that was not there before creating the views Step 7: comment out everything in the click event Step 8: uncomment Ti.UI.createView(); Step 9: run the app and click the window Step 10 notice that the memory used jumps up and is not released

var win = Ti.UI.createWindow({backgroundColor:'white'});
var testView = null;

win.open();

win.addEventListener('click', function(e){
	if(testView){
		win.remove(testView);
		testView = null;
	}else{
		testView = Test.init();
		win.add(testView);
	}
	
	// Ti.UI.createView();
});

var Test = (function(){
	function init(){
		var view = Ti.UI.createView({
			height: 200,
			width: 200,
			bottom: 20,
			backgroundColor:'blue'
		});
		
		for(var i = 0; i < 100; i++){
			view.add( Ti.UI.createView({backgroundColor: 'red'}) );
		}
		
		return view;
	};
		
	return {
		init: init
	}
})();
