    Default TreePanel store can't bind to viewModel store

    SA: 4.2 and ExtJS 6.5 Classic

    Step to reproduce:
    o create a new project based on the last layout example: "Header / Content/ Left Tree Menu"
    o duplicate the MenuStore to MenuStore1
    o drag/drop MenuStore1 to the viewmodel of "My Viewport"
    o fill the name of the viewmodel store to be "menus"
    o change the store of the menuPanel to use binding and use {menus} for the store

    ==> you should get the error:
    Framework Error: Uncaught TypeError: store.getRoot is not a function
