No way to use a custom turn server port

Evironment details:

• OS: Ubuntu 20.04
• Jami version: Jami from jami.net for ubuntu 20.04

Steps to reproduce

• Set your own turn server using these instructions: https://git.jami.net/savoirfairelinux/ring-project/wikis/technical/3.6-Setup-your-own-TURN-server
• Update turn configuration on Jami advance settings with: IPOfTurnServer:customPort
• Then trying to make a call using turn only will not work and the logs will show this line: [ice] added turn server 'IPOfTurnServer', port 3478

The solution is to use 3478 as the listening port on the turnserver.conf than everything will work as intended.
