I am going to do the following in order to reduce the issue with
littering `user-emacs-directory':

1. When there is no data stored by org-persist (e.g. when the user
   disabled `org-element-cache-persistent' and never uses image
   downloading), do not write anything and do not create the empty
   index.

2. `org-persist-disable-when-emacs-Q' will redirect
   `org-persist-directory' to a temporary directory.
   (this is a bugfix)
   
3. Users who think that org-persist is still on the way may set
   `org-persist-directory' explicitly to, say,
   `temporary-file-directory'.

Let me know if there are any objections.
