Manually pulling back a GtkTreeViewColumn fix from treeview-refactor-staging

Browse Source 
This fix has evolved in the staging branch since all column members are
on a private structure, but since it causes warnings when closing the
windows of the testcellarea test (because the combo-boxes use a treeviewcolumn)
I thought it nice for now to just manually include the fix.

The fix is just proper bookkeeping of delegate objects at dispose() time.
