Thanks for the PR!
Looks good to me!

I've confirmed that this PR's code change makes Android's tint behave exactly like iOS' for both masked images and completely opaque images (such as camera photos).

---

Side Note:
The only thing I don't like is iOS and Android's tinting behavior of opaque images (no alpha; such as photos). I would expect a "tint" to apply a color blend effect like how it works in Photoshop. But instead you see a solid color (the tint color) completely covering the image. But the only way to achieve this color blending effect is to grayscale the image first, then apply the tint color. I'm pretty sure this can be achieved via a single custom color matrix to the image view.
(I don't think this should stop this PR. This is how it works on iOS. I just don't like the behavior.)

@jquick-axway I made titanium-image-filters exactly for that :). Or you can use masked image filters that are available in the SDK as well.

@garymathews The unit test failures seem unrelated, but maybe critical: Error: expected Object {} to be '#ff1f1f'

FR Passed: Able to see the tint applied to the following test case (https://jira.appcelerator.org/browse/TIMOB-27721) :

const window = Ti.UI.createWindow();
const icon = Ti.UI.createImageView({
tintColor: 'red',
width: 30,
image: 'example.png'
});
window.add(icon);
window.open();
