Edje: invalidate double named group

What happens if a group has 2 name statements("double named")?
edje will fail to free the groups cache while shuting down due
the collection directory entry hash having two entries with
different names but pointing to the same object - the second try
to free the part mem pool will fail - since it was freed before -
and issue an abort.
