commit 6605e08c1775ccccf979887b17c6ad41d4cc78f9
Author: Noboru Ota <me@nobiot.com>
Commit: Protesilaos Stavrou <info@protesilaos.com>

    Add "no backlink" user-error 'denote-link-find-backlink'
    
    'denote-link-find-backlink' emits a user-error when no backlink is found
    for the note.  The same should be done for 'denote-link-find-backlink'.
