fix(android): Ti.UI.Tab selected event returns no data

[m1ga]

Currently the Ti.UI.Tab selected event doesn't return the values it should be according to the docs. The issue is that the data is set to null instead of focusEventData

Test

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();
