Change in some functions from JWT

Change in some JWT functions

In the auth/JWT.cpp file, in the line:

payload->userId = decoded.get_payload_claims().at("userId").as_string()

It looks like it should now be:

payload->userId = decoded.get_payload_claim("userId").as_string()

In the file auth/JWT.hpp, in the line:

jwt::verifier<jwt::default_clock, jwt::picojson_traits> m_verifier;

It looks like it should now be something like:

jwt::verifier<jwt::default_clock, jwt::traits::kazuho_picojson> m_verifier;
