ICE - resort the check list after adding prflx candidates
The check list is not sorted after adding new prflx candidates, which can cause the nomination of candidates pairs with less priority.
See https://github.com/pjsip/pjproject/pull/2806
[EDIT] The patch was reverted until issue https://git.jami.net/savoirfairelinux/ring-daemon/-/issues/627 is resolved
