[TIMOB-7790] Android: UI.Animation - orientation change resets animation to original state

Problem

When running an intro animation or creating a window animation fade with opacity from 0 to 1, a change in orientation resets the animation state of the window to its original created state and the animated end state.

Test case

Here is a use case followed by a code example of this problem. I have an app with 2 different splash screens based on portrait and landscape orientation. My app consists of a single window that has a few UI elements, labels such like within, the window is created with an opacity of 0. When the app loads, it triggers an animate function to take the opacity to 1. As the window has 2 orientation states, when the user flips the device in either direction, the original window state is restored and, thus, the opacity of the window becomes transparent (reverts to 0), which causes the splash screen to show through.

Ti.UI.setBackgroundColor('#fff');
var win1 = Ti.UI.createWindow({
	title : 'Anim Test',
	backgroundColor : '#fff',
	exitOnClose : true,
	navBarHidden : false,
	opacity : 0
});
win1.orientationModes = [Ti.UI.PORTRAIT, Ti.UI.LANDSCAPE_LEFT];
var label1 = Ti.UI.createLabel({
	color : '#000',
	text : 'Main Application Window, after fade.',
	font : {
		fontSize : 20,
		fontFamily : 'Helvetica Neue'
	},
	textAlign : 'center',
	width : 'auto'
});

win1.add(label1);

win1.animate({
	opacity : 1,
	duration : 3000
});
win1.open();
