These tests began failing on snapshots after changes in
Spring Framework's `DispatcherServlet` to reset the response
on an error.
For now, we can have these tests operate with a 200 OK response.
An issue was opened in the spring-framework issuer tracker to
discuss this and address `CorsFilter` (and any other filter) that
writes headers that would be cleared on an error.
