radix tree test suite: Fix leaky tests 



If item_insert() or item_insert_order() failed to insert an item, they
would leak the item they had just created.  This was causing runaway
memory consumption while running the iteration_check testcase, which
proves that Ross has too much memory in his workstation ;-)

Make sure to free the item on error.  Found with -fsanitize=address.
