When a new stun request hits a valid pair, of a failed component, we may
have a transition from state failed to connected. In this situation, we
do a logical progression failed -> connecting -> connected, like we do
in function priv_update_check_list_state_for_ready()

Similarily, when a new stun request hits a failed pair, of a failed
component, triggering a new conncheck for this pair may also cause the
component state to move back from failed to connecting state.
