feat(android): parity for Tab.popToRootWindow()

[m1ga]

An iOS TabGroup opens Windows inside of it and you can use Tab.popToRootWindow() to close all those tabs. Since Android is opening new windows we don't have that stack and can close them.

The idea is to emulate that behavior by looking at the first activity and check if it is a TabGroup. If so loop through all activity above it and close them.
Works with style: Titanium.UI.Android.TABS_STYLE_BOTTOM_NAVIGATION too.

Test:

var win = Ti.UI.createWindow();
var btn = Ti.UI.createButton({
	title: "open"
})
win.add(btn);

btn.addEventListener("click", function() {
	createWindow();
})

function createWindow() {
	let newWin = Ti.UI.createWindow({
		backgroundColor: "#fff"
	});
	newWin.addEventListener("close", function(e){
		console.log("closing window");
	})
	tab1.open(newWin);
	let newButton = Ti.UI.createButton({
		title: "close",
		bottom: 100
	})
	let newButton2 = Ti.UI.createButton({
		title: "new"
	})
	newWin.add([newButton, newButton2]);
	newButton.addEventListener("click", function() {
		tab1.popToRootWindow();
	});
	newButton2.addEventListener("click", function() {
		createWindow()
	});
}

var tab1 = Ti.UI.createTab({
		window: win,
		title: 'a'
	}),
	tab2 = Ti.UI.createTab({
		window: Ti.UI.createWindow(),
		title: 'b'
	}),
	tabGroup = Ti.UI.createTabGroup({
		tabs: [tab1, tab2]
	});
tabGroup.open();

• start the app.
• open some windows and then press close
• you should go back to the TabGroup again

Todo:

• Test it 😄 Draft for now as I only tested it with the small demo above

@m1ga Can you give me an update on a few of your Draft PR's? Many of them are super interesting and I wonder if you just missed to change the state after finishing work on them.

I just don't use this in any app so I don't have many test data to verify it doesn't have side effects. It's only still a draft as I don't have any infos besides this one demo that it is working 😄 It was requested on Slack from time to time so I've added this but no one tested it.

I'll change it to ready for review so we can get some more people to test it
