fix(android): backgroundColor in TextField

[m1ga]

The Material library was updted from 1.6.2 to 1.12.0 recently. In 1.7.0 there was a new "Shape theming" added (more info). This change added a new drawable that is not removed when trying to set a background color. According to these attributes we should change boxBackgroundColor to set the color.

var win = Ti.UI.createWindow();
var view = Ti.UI.createView({
	backgroundColor: "#666",
	width: 200,
	height: Ti.UI.SIZE,

})
var tf = Ti.UI.createTextField({
	width: 100,
	// borderStyle: Titanium.UI.INPUT_BORDERSTYLE_NONE,  // better way to do it
	backgroundColor: "red",
});
setTimeout(function() {
	tf.backgroundColor = "blue"
}, 2000)
view.add(tf);
win.add(view);
win.open();

Textfield will have a red and blue background (after 2 sec).
