Fixed requests returning `500 Internal Server Error` when the header selected by `request_ip_source` is absent, duplicated, or malformed (for example Envoy omitting `X-Envoy-External-Address` on internal requests). The client IP now falls back to the connection peer address instead of failing the request. Contributed by @eleboucher
