[TIMOB-27512] Android: hideSoftKeyboard() not working as of 8.2.1

*Issue:* Soft Keyboard is not hiding using this method "Ti.UI.Android.hideSoftKeyboard()" on android version 8, 9 and 10. It works as expected with Ti SDK 8.2.0.GA but does not work with TI SDK 8.2.1.GA Please see the attached gif image. Same code using 8.2.1.GA left side, using 8.2.0.GA right side. *Steps to Reproduce:* 1. Run the following sample code on an android device or emulator. 2. Click on the textField for appearing keyboard. 3. Then click on the button for hiding it.

	var win = Ti.UI.createWindow({
		backgroundColor : 'white',
		layout : "vertical"
	});

	var textField = Ti.UI.createTextField({
		backgroundColor : '#fafafa',
		color : 'green',
		width : 250,
		top : 30,
		height : 40
	});

	// Create a Button.
	var test = Ti.UI.createButton({
		title : 'test',
		height : 50,
		width : 100,
		top : 30,

	});

	// Listen for click events.
	test.addEventListener('click', function() {
		Ti.UI.Android.hideSoftKeyboard();
	});

	win.add(textField);
	win.add(test);
	win.open();

*Expected Result:* It should hide the keyboard after clicking. *Work-Around:* Use the TextField object's blur() method instead. This still hides the keyboard in 8.2.1. However, it will also remove the focus from the TextField which might not be what you want.
