[SA-1536] Dont send STUN binding req with turn

[NicoleHippolite]

From what I can tell, the turn server stops being contactable after 10mins which causes these STUN BINDING requests to fail and causes the ICE state to be set to disconnected. I have tested this locally by just not sending these BINDING requests when using the TURN client instead of the STUN client and was live for an hour before the bumper rolled - which indicates that they're not necessary. This will only affect TURN PC's and has no impact on STUN PC's

NOTE: all I've done to the below code is add the if (pair?.protocol?.type !== "turn") { condition around what's already there

Given this is not actually a fix for whatever is causing the turn server to become uncontactable - I am not requesting this code gets merged into the shinyoshiaki repo

I have a Jira task SA-1617 that tracks the investigation into the actual turn server issue so we dont remain on the forked version of werift
