Bug 419707 - GridTreeViewer remove-by-index broken

In GridTreeViewer, the following method 
public void remove(final Object parentOrTreePath, final int index) 
seems to be a copy-paste of the same method in the "classical"
TreeViewer. 

In particular it does
   Tree tree = (Tree) getControl();
instead of 
   Grid tree = (Grid) getControl();

and  

   TreeItem item = tree.getItem(index);
instead of 
   GridItem item = tree.getItem(index);
