[TIMOB-23653] Windows: Animation returns to original opacity property when finished

Description

When using the code below, when the animation is complete the opacity property will be what it was set to before the animation started.

var win = Ti.UI.createWindow({backgroundColor: 'red'}),
    img = Ti.UI.createImageView({width: '80%', height: '80%', image:'Logo.png', opacity:0.5});
 
var anim = Ti.UI.createAnimation({
	opacity:1,
	duration:1000
});

win.addEventListener('click', function(){
	img.animate(anim);
});

win.add(img);
win.open();

*This a regression that first appears in 5.3.0.GA,* *Workaround* As a workaround add an eventListener for the complete event and then set the property as required like below

anim.addEventListener('complete', function(){
	img.opacity = 1;
});
 

Steps to reproduce

Using the code above, build for Windows Platform appc run -p windows -T wp-emulator -C 10-0-1

Click the screen

Actual result

At the end of the animation the opacity of the image will return to the original value

Expected

The value at the end of the animation should be what is defined in the animation
