[TIMOB-8102] iOS: Ti.UI.WebView crashes when a malformed URL has been entered

*Code*

var win = Ti.UI.createWindow();

var webView = Ti.UI.createWebView({ 
	width: '100%', 
	height: '100%'
});

win.add(webView); 
webView.url = 'http:// google.com'; // if you remove the space, it works fine in 1.8.2

win.open();

*Expected behavior* The app should run without crashing, just like it does when using the same code and building with version 1.7.5. *Actual behavior* The app crashes at runtime. *Notes* -I have only tested this on the iOS simulator. -It works fine when you enter a correct URL (i.e. without any spaces), however in 1.7.5 you could have a space and it wouldn't crash. -Current workaround: http://pastebin.com/jPkDBK5u -HD ticket: http://support-admin.appcelerator.com/display/APP-584755
