Use of "system.playlistspath" setting instead of default profile one where missing

I find out in two classes "special://profile/playlists" string is used instead of the setting option "system.playlistspath" to check if it's the playlist path.
I don't know what is the result in the UPNP server but in the FileUtils playlists results as not allowed to access from remote so you can't load playlists with "Files.GetDirectory".
I removed it because playlists in special://profile/playlists are not displayed in video -> playlists if you change the playlists path. If they have playlists there aren't displayed. But I suppose it's something we can translate without problems
