[TIMOB-6699] Android: ImageView added to window with no height/width specified does not scale to window (parity bug)

Fail Case / Test Case

1. Create a new app. 2. Replace the new app's app.js with the one here below. 3. Run the app.

Symptom

When the app window opens, it'll just get the small KS_nav_ui.png image on it (in the fail case -- if you're testing the fix, you should see the image expanded and scaled to the window.) In iOS, if you run this app, it will expand/scale to the window.

Titanium.UI.setBackgroundColor('#000');
var win = Titanium.UI.createWindow({  
    title:'Test',
    backgroundColor:'#000',
	exitOnClose: true
});

win.add(Ti.UI.createImageView({
	image: "KS_nav_ui.png"
}));


win.open();
