Currently the httpd doesn't serve private projects, so this test fails
everytime.
We should look at it again once we figured out how to serve private
projects securely.
- Handle ResponseParseErros, ResponseErrors and normal errors
differently.
- Show them all in the same `LoadError` view
- Add a subtitle to give users some more information on what could have
gone wrong.
- Add more properties to the copyable error message to make debugging
easier.
