fix(android): Fix Up button flickering when clicked in NavigationWindow

[ypbnv]

JIRA: https://jira.appcelerator.org/browse/TIMOB-27190

Description:
The Up button disappears before the Window is actually closed when this is done in a
NavigationWindow's Windows stack.
This was happening due the displayOptions flags being set after the ActionBar is drawn and immediately before closing the Window. In this PR setting the child Window's showHomeAsUp is done through the ActionBarProxy class instead of directly the SupportActionBar instance.

Note: This is a visual fix so there is no unit test for it.

Test case:

const win1 = Ti.UI.createWindow(),
	win2 = Ti.UI.createWindow(),
	navWin = Ti.UI.createNavigationWindow({ window: win1}),
	but = Ti.UI.createButton({ title: 'Nav'});
navWin.open();
win1.add(but);
butt.addEventListener('click', () => {
	navWin.openWindow(win2);
});

There is a short clip in the JIRA ticket that demonstrates what is the mentioned flicker.
