TURN caching issue
- Use Jami
- Close the computer
- Re-open it
- A connectivity change occurs and TURN is re-cached.
If the TURN is available, the cache should be correctly updated
Sometimes the cache is deleted
NM is giving the connectivity change before that the network is really available, so the resolution can give a "network unreachable". Instead of that, we should wait that the DHT is connected (so that we are ready to use Jami).
