This adds generating a static 500 status page when a `pages/500.js` file is added similar to how we handle generating static 404 pages when `pages/404.js` is present. This allows showing a customized error page when a 500 error occurs in an optimal way.
jest retries seem to be masking test failures, like the `auto-export` one (and maybe others). I turned it off for now. The `auto-export` test fails when retries are turned off.
the output of this test failure was a bit unhelpful so I also improved it.
Many tests have anonymous page functions.
