    emacs: Set 'guix-buffer-item' before displaying entries.
    
    * emacs/guix-buffer.el (guix-buffer-set): Set 'guix-buffer-item' early,
      so that it can be used during displaying entries.  For example, this
      allows us to use a value of the current guix profile when package
      entries are inserted in a "List" or "Info" buffer.
