[TIMOB-26284] Android: Cannot add child-views to views extending UIFragment

When using Ti.Map to create a map-view, sub-views of the map are not being displayed. This is not the case for iOS. A reproducible test-case can be done by taking the module's example app.js and trying to add a child view to it:

var Map = require('ti.map');
var win = Titanium.UI.createWindow();

var mapview = Map.createView({

});

mapview.add(Ti.UI.createView({
  width: 50,
  height: 50,
  backgroundColor: 'red'
}))

win.add(mapview);
win.open();
