Add request method and url to error message

What does this MR do?

Add HTTP method and request URL to error message, should make it easier to debug https://sentry.io/foodsaving-worldwide/foodsharingde-beta-frontend/issues/637098658 and similar.

How confident are you it won't break things if deployed?

I promise to fix it if it breaks.
