Update ERC-7573: added keyEncryptedSeller to ILockingContract TransferConfirmed event

[Julius278]

added the already existing keyEncryptedSeller param to the ILockingContract TransferConfirmed event.

/**
* @dev Emitted when the transfer for the token is incepted
* @param id the trade identifier of the trade.
* @param amount the number of tokens to be transferred.
* @param from The address of the seller.
* @param to The address of the buyer.
* @param keyEncryptedSeller Encryption of the key that can be used by the seller to reclaim the token in case of cancellation or failed payment.
* @param keyEncryptedBuyer Encryption of the key that can be used by the buyer to claim the token in case of a successful payment.
*/
event TransferConfirmed(bytes32 id, int amount, address from, address to, string keyEncryptedSeller, string keyEncryptedBuyer);`

In this case its easier to call transferAndDecrypt (buyer) or cancelAndDecrypt (seller) without further interaction with the ILockingContract

I wanted to make changes to this PR in a review, but I do not have the rights... (or I do not know how to do it :).

I do not understand why the tests are failing. This looks like a GitHub issue.
