fix(android): focus event in TabGroup

[m1ga]

12.3.1 added more paremeters in the selected event of the TabGroup in this PR: https://github.com/tidev/titanium-sdk/commit/abc9e81bd38c01bc3de48219707aa4d1d06e94fe

It looks like the data is cleared before the focus event arrives so it won't appear in JS. I still see it in the logs: [/home/miga/tools/titanium-sdk/android/runtime/v8/src/native/V8Object.cpp:89] firing event "focus" but nothing inside the app.

When cloning the data it arrives

Test code

const tabGroup = Ti.UI.createTabGroup({
    tabs: [Ti.UI.createTab({
        window: Ti.UI.createWindow(),
        title: 'Tab 1'
    }), Ti.UI.createTab({
        window: Ti.UI.createWindow(),
        title: 'Tab 2'
    })]
});

tabGroup.addEventListener('focus', event => {
    console.warn('FOCUS', tabGroup.activeTab);
});

tabGroup.open();

and the old code from the selected PR

var win1 = Ti.UI.createWindow();
win1.add(Ti.UI.createLabel({text: 'I am a blue window.'}));

var win2 = Ti.UI.createWindow();
win2.add(Ti.UI.createLabel({text: 'I am a red window.'}));

var tab1 = Ti.UI.createTab({
    window: win1,
    title: 'Blue'
}),
tab2 = Ti.UI.createTab({
    window: win2,
    title: 'Red'
}),
tabGroup = Ti.UI.createTabGroup({
    tabs: [tab1, tab2]
});

tab1.addEventListener("selected", function(e){
  console.log(e.index, e.previousIndex)
})
tab2.addEventListener("selected", function(e){
  console.log(e.index, e.previousIndex)
})

tabGroup.open();
