Refactor Org Mode link finder function 

The main entry point is now `db/org-find-links-to-current-item', which decides
how to obtain the ID and CUSTOM_ID of the item to look for.  The main work is
done by `db/org-find-items-linking-to-id', which does some checks, build the
query, and then calls `org-search-view' (which, indeed, does the actual work).
Users should call `db/org-find-links-to-current-item' only.
