Title: Fix request loop on non-stale nonce with time_limit parameter.

On HTTP Digest auth (MD5), when `Rack::Auth::Digest::Nonce.time_limit` is set, `stale?` function of `Nonce` always returns `false`. So user-agent's re-challenges never succeed. As a consequence, request-response infinitely loops.
