I don't see what that commit has to do with it.

This is a regression in emacs 26. How to reproduce:

(defun test () "" nil) ;; insert text in buffer *scratch*
C-M-x ;; eval-defun (adds an entry to load-history with null file)
C-h f package- TAB ;; crashes

This is caused by `help--loaded-p' not handling nil entries, introduced
in 0c31ff43b6880c84498fbe1f06e1e5809b55e838.
