Index mismatch in secret_share check of to_round_2()

[Nashtare]

In the Key Generation process, part 2 step 2, the participant is checking every received commitments from other participants.
This is being done as below:

frost-dalek/src/keygen.rs

Lines 551 to 555 in 9645caf

	for share in my_secret_shares.iter() {
	// XXX TODO implement sorting for SecretShare and also for a new Commitment type
	for (index, commitment) in self.state.their_commitments.iter() {
	if index == &share.index {
	share.verify(commitment)?;

However, the indices in my_secret_shares will always be equal to the current participant index, while the indices in their_commitments will be indices of the other participants (all but the one we are trying to match actually). This skips completely the share verification.
