conncheck: honor the retransmit flag in case of role conflict

This other rare situation happens when a role conflict is detected by an
stun reply message, on a component that already has a nominated pair
with a higher priority. In that case, the retransmit flag should be
honored, and the pair with "role conflict" should not be retransmitted.
