Title: Handle missing templates when rendering custom errors

If the user has defined a custom exception bound to a custom `rescue_response` and the view cannot be found in their application (and because it’s obviously not found in Gaffe) we want to catch that and throw the default `internal_server_error` page, instead of Rails’ failsafe no-style error page.
