fix(android): use correct dark/light mode image for Buttons

[m1ga]

Add an image "test.png" to platform/android/res/drawable/ and platform/android/res/drawable-night/ (classic app)

const window = Ti.UI.createWindow({ backgroundColor: '#fff' });

const btnWithImage = Ti.UI.createButton({
	image: '/images/test.png',
	top: 200, left: 20,
	width: 150, height: 150
});

const imageView = Ti.UI.createImageView({
	image: '/images/test.png',
	top: 200, right: 20,
	width: 150, height: 150
});

window.add([btnWithImage, imageView]);
window.open();

and change dark/light mode using adb shell "cmd uimode night yes" and adb shell "cmd uimode night no"

Changes:

• will use the dark/night mode image for the button
• normal ImageView will also update, even if you don't restart the app (clearing TiImageCache.clear();)
