MOSYNC-3128

Info:
setting the title of a screen after it has been added as a tab screen child now looks if the parent is a tab screen and if so, searches for the screen and updates its title; I modified the TabScreenTest program: the second screen title is now set after the screen has been added to the tab screen

Fix:
commit bf056c2ab4b86db55c86a5306f3f22122175c146
