lan: improve pjsip behavior in a LAN

1. Resolving the TURN server but receiving connection timeout are
breaking the ICE init for now. This should not be the case. This
patch only removes the candidate from the candidate's list if a
conection timeout to the TURN occurs.
2. pj_getaddrinfo is very slow. Moreover, it's unecessary because
we succeed to get correct hosts candidates. So, just disable this.
