[TIMOB-11405] Android: TextField - Black bar appears if soft keyboard is invoked

Description: Black bar appears above the text field if soft keyboard is invoked. Not a regression, the behavior exists as far back as 2.1.2 at least. Steps: 1. Run the following code:

var _window = Ti.UI.createWindow({backgroundColor: '#336699'});
		
		var textField = Ti.UI.createTextField({
			backgroundColor: '#fff',
			height: 30,
			top: 20,
			left: 20,
			right: 20
		});
		
		_window.add(textField);
		_window.open();

2. Focus the text field to invoke the soft keyboard, if it's not invoked yet. Expected: Should not see black bar above the text field Actual: Black bar appears
