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({});
	newWin.open();
	let newButton = Ti.UI.createButton({
		title: "close",
		bottom: 0
	})
	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
