Error: Failed to set remote answer sdp: Called in wrong state: kStable;

@kdowney @sengelman I was able to determine that his issue was caused by a bug present in both the example code and my app's code:

private void OnPermissionGranted(string permission)
        {
            grantedPermissions.Add(permission);
            if (grantedPermissions.Count == requiredPermissions.Length)
            {
                StartAfterPermissions();
            }
        }

On the second connection attempt, if grantedPermissions still contains the results from the first connection, StartAfterPermissions will get executed multiple times in quick succession causing the wrong state error.

However, if we clear the grantedPermissions before the second attempt, the second connection will be successful.
