* Wrap a node reference as NavigationItem, to inject into IDEA's services that demand {@link NavigationItem} or {@link ItemPresentation}, like Go To.
*
* Note, there's no reason to use NavigationItem in <code>ChooseByNameModel</code> subclasses suited for navigation within MPS, as we could handle it much
* more efficiently with unwrapped objects, there's almost no value in NavigationItem (except reuse of NavigationItemListCellRenderer).
