Set default Error status code to 404 (#6276)
* Set default `Error` status code to 404

This is an appropriate default behavior because:

1. When the server encounters an error, the `err` property is set.
2. When the client-side application crashes, the `err` property is set.

This means the "only" way to render the `/_error` page without an error
is when a page is not found (special condition).

Fixes #6243
Closes #5437

* Add new integration test for client side 404

* single quotes

* Remove unused variable

* Standard needs to go away

* Whoops

* Check for null status code in res and err

* Only check response for valid statusCode
