fix(android): return 0 for recycled images when clearing cache

[m1ga]

When TiBlobLruCache.getInstance().evictAll(); is called it will currently display:

[WARN]  Bitmap: Called getRowBytes() on a recycle()'d bitmap! This is undefined behavior!
[WARN]  Bitmap: Called getHeight() on a recycle()'d bitmap! This is undefined behavior!

This fix will check if it is recycled or not and then just return 0 and not try to calculate the size.

Test

var img = Ti.UI.createImageView();
var win = Ti.UI.createWindow();

win.addEventListener("click", function() {
	Ti.Media.showCamera({
		success: function(event) {
			img.image = event.media;

			var f1 = Titanium.Filesystem.getFile(Titanium.Filesystem.applicationDataDirectory + "/image3.jpg");
			f1.write(event.media.imageAsResized(20, 20));
		}
	});
});

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