    main: Fix drag'n'drop ordering on the playlist
    
    Since made the processing of playlists asynchronous, adding files
    to the playlist didn't insert them at the position we told them to,
    because the ->tree_path used to check where to insert it was freed
    before we had any chance to process the added MRLs.
