[TIMOB-9786] iOS: WebView - Webview does not display correctly after first orientation change.

Webview does not display correctly after first orientation change of the device. This is regression. This issue does not occur on 2.0.2 GA Steps to reproduce: 1. Create an app using the code below. 2. Launch the app in portrait mode. Let the webpage load. 3. Change the orientation to landscape. Actual: The display of the screen gets distorted. (eg. On appcelerator home page, white background of the lower half screen turns to black on right half) Expected: The display of the screen should remain same on orientation change.

Titanium.UI.setBackgroundColor('#000');

var win = Titanium.UI.createWindow({  
    title:'Tab 1',
    backgroundColor:'#fff'
});

var webview1 = Ti.UI.createWebView({
			url : 'http://www.appcelerator.com'
		});
win.add(webview1);

win.open();
