[TIMOB-3122] iOS: ImageView animation ignores repeatCount upon second call to start()

var win1 = Titanium.UI.createWindow({
    backgroundColor: '#fff'
});

var image_list = ["default_app_logo.png", "apple_logo.jpg"];

var animation = Ti.UI.createImageView({
    images: image_list,
    repeatCount: 1,
    duration: 1000
});

win1.addEventListener("singletap", function(e) {
    Ti.API.log("info", "Starting because of single tap.");
    Ti.API.log("info", "repeatCount is: " + animation.repeatCount);
    animation.start();
});

animation.addEventListener("stop", function(e) {
    Ti.API.log("info", "animation shutting down properly");
});

win1.add(animation);
win1.open();
