Fix bookmarking/reloading after saving shuffled playlist

The resume index into the playlist file
that was used for bookmarks created immediately
after saving a shuffled playlist, or for reloading
the saved playlist (in case "Reload After Saving"
was enabled), tended to be incorrect.

The playlist file effectively isn't shuffled
anymore after saving it to a file, but the
resume index may still have to be rotated unless
playback has been stopped and resumed before
bookmarking, due to indices that are shifted
by first_index.
