      Description

      Originally reported in WT-3135, as it seems to be related to fixes made for that report.
      Dmitri Shubin reports:

      Attaching test that shows the problem I see when duplicating index cursor.
      When running on current master (13d9445) I get:

      $ ./index_cursor_dup
      adding new record
      positioning index cursor
      index_compare: ikey1 = 17, pkey1 = <empty>, ikey2 = 17, pkey2 = 13
      index_compare: ikey1 = 17, pkey1 = <empty>, ikey2 = 17, pkey2 = 13
      index_compare: ikey1 = 17, pkey1 = <empty>, ikey2 = 17, pkey2 = 13
      index_compare: ikey1 = 17, pkey1 = <empty>, ikey2 = 17, pkey2 = <empty>
      duplicating cursor
      index_compare: ikey1 = 17, pkey1 = 13, ikey2 = 17, pkey2 = 13
      index_compare: ikey1 = 17, pkey1 = 13, ikey2 = 17, pkey2 = 13
      

      But on develop (a8fe040):

      $ ./index_cursor_dup
      adding new record
      positioning index cursor
      index_compare: ikey1 = 17, pkey1 = <empty>, ikey2 = 17, pkey2 = 13
      index_compare: ikey1 = 17, pkey1 = <empty>, ikey2 = 17, pkey2 = 13
      index_compare: ikey1 = 17, pkey1 = <empty>, ikey2 = 17, pkey2 = 13
      index_compare: ikey1 = 17, pkey1 = <empty>, ikey2 = 17, pkey2 = <empty>
      duplicating cursor
      index_compare: ikey1 = 17, pkey1 = 13, ikey2 = 17, pkey2 = 13
      index_compare: ikey1 = 17, pkey1 = 13, ikey2 = 17, pkey2 = <empty>
      session->open_cursor(session, NULL, cursor, NULL, &cursor1) at (index_cursor_dup.c:110) failed: No such file or directory [2]
      

      Probably the reason is that collator should handle absence of primary keys a bit differently.
      Please advise.
