vim-patch:9.1.1739: Matches may be listed twice with wildmode=longest,list

Problem:  Matches may be listed twice with wildmode=longest,list when
          "longest" doesn't change command line (after 9.1.1737).
Solution: Set did_wild_list when trying "list" after "longest"
          (zeertzjq).

closes: vim/vim#18227
