daemon: ICE init fails when TURN server is not accessible
Issue generated from Tuleap's migration script. Originally submitted by: Guillaume Roguez (guillaume)
When a TURN server is given to use for an account, the ICE initialization will fails (by timeout) if the TURN server is not accessible (i.e. not resolvable or not responding to STUN registers msg).
As it's the init step of ICE and not negotiation, the ICE may negotiate but we don't let a chance to do it.
As example, this causes calls to failed even when peers are both joinable with their private host addresses
