[PATCH 1/1] emms-source-playlist.el: add native playlist to cache

The function for parsing native playlists doesn't use the emms-track
constructor because the data is already in the correct format.  However
this means that it misses the call to `emms-cache-set-function`, meaning
that the playlist doesn't get added to the cache and the emms-browser.
