Describe the bug
Exporting a PDF fails with the following error (when debug is enabled):
Trying to get property 'name' of non-object (View: /srv/www/bookstack/v21.04/resources/views/partials/entity-export-meta.blade.php)

Steps To Reproduce
I've got the feeling this is caused by the original creator of the page being removed from bookstack, since the revision page of the page shows a lot of 'Deleted User', including the Initial publish.

Expected behavior
I expect that the pdf export still works

Screenshots

Your Configuration (please complete the following information):

Exact BookStack Version (Found in settings): v21.04
PHP Version: PHP 7.3.27-1~deb10u1
Hosting Method (Nginx/Apache/Docker): Apache

Additional context
I removed line 8 from entity-export-meta.blade.php and the export works as expected.
