Think about deterministic improvements for Split logic

[SpontaneousOverthrow]

The main idea here is to refactor this function

	for _, store := range stores {
		for id := range peers {
			peerExists, _ := regexp.MatchString(filepath.Base(store.Location)+":.*", peers[id])
			if peerExists {
				participantsIDs = append(participantsIDs, id)
			}
		}
		for _, wallet := range store.Wallets {
			for account := range wallet.Accounts(ctx) {
				key, err := service.GetAccountKey(ctx, account, passphrases)
				if err != nil {
					fmt.Println("Error")
				}

				accountDatas[account.Name()] = append(
					accountDatas[account.Name()],
					key,
				)
			}
		}
	}

We need to have ParticipantID accountName and key in one data struct(struct or hash map) to prevent nondeterminism

sort of fixed here #49 need more tests
