bookmarks: show 'Create Bookmark' for unsaved playlists

Instead of hiding this option when the current playlist
is unsaved, we can offer to save the playlist, if
necessary, before attempting to create a bookmark.

This simplifies the workflow by getting rid of steps 1
and 2 that a user currently needs to perform:

1) Open context menu, check if "Create Bookmark" option
   is available
2) If not: Re-open context menu. Select Current Playlist
   -> Save Current Playlist
3) Re-open context menu. Select Bookmarks
   -> Create Bookmark
