Fix ets:select hanging on ordered_set with empty list as key.
erl_db_tree.c incorrectly used NIL (empty list) as "lastkey" to mark start of the iteration. A real NIL key could then cause a select or match iteration to be restarted over and over again if the last key before a trap happended to be NIL. Changed NIL to THE_NON_VALUE. Should be ok as the initial key value can never be put into any continuation tuple.
