My most hated JuK bug in 3.4 (so this will be backported shortly) -- when

switching playlists the setSearch() call was being called before visiblePlaylist()
reported the new playlist, so it was basically clearing the search term for the
playlist that was about to go to the background.  This meant that when you switch
back to it your search is cleared.
