Fix wrong handling of EMMS' current playlist buffer during export 

The macro `with-current-emms-playlist' does not set the current playlist to the
current buffer, but instead switches to it.  Yes, that's reasonable, but not
what I thought it does.  Since I need the reverse (make the current buffer to
temporarily be the current playlist), we simply bind `emms-playlist-buffer' to
the value returned by `current-buffer'.

While we are at it, also make info loading synchronous by binding
`emms-info-asynchronously' to nil.
