TypeError: Argument 1 passed to Drupal\Core\Entity\EntityViewBuilder::view() must implement interface Drupal\Core\Entity\EntityInterface, null given, called in core/modules/node/node.module on line 559

Ran into this on an existing large site; this was a database integrity issue for me. Some nodes were somehow owned by deleted users, when rendering them in a search result I saw the same error.

> \Drupal\node\Entity\Node::load(71137)->getOwner();
= null

As getOwner() can return NULL (even though it is not documented as such) I think we should provide protection against this.

This also reminds me that all these historic theme settings should just be configured in the entity display.

Seems OK to be more defensive here, there are other ways to find out the node owner has been deleted that aren't fatal errors for site visitors.

Committed/pushed to 11.x and cherry-picked back through to 9.5.x, thanks!
