 `rend_service_derive_key_digests()` calculates service ID before key
 digest. But service ID depends on key digest. So if digest calculation
 fails it will appear in log as `Internal error: couldn't encode service
 ID.` not as `Couldn't compute hash of public key.`.

 btw, what's the point of `Internal error: `  prefix?
