Do not change playlist item title on media end

The original implementation changed the playlist item title to
"Inaccessible item" on video end as a workaround for when the next
autoplay playlist item was inaccessible. This is because the title
does not otherwise update when an item has a blank canvas. This
workaround was insufficient and caused unintended behavior when autoplay
was not on. Issues with item title not updating will be handled in #5497.
