Fix an undesired breaking changed introduced by #2747 : 1. The fields `eth_helper_contract_address` and `erc20_helper_contract_address` in `get_minter_info` were wrongly reused to point to the new helper smart contract [0x18901044688D3756C35Ed2b36D93e6a5B8e00E68](https://etherscan.io/address/0x18901044688D3756C35Ed2b36D93e6a5B8e00E68) that supports deposit with subaccounts and that was added as part of proposal [134264](https://dashboard.internetcomputer.org/proposal/134264). 2. This broke clients that relied on that information to make deposit of ETH or ERC-20 because the new helper smart contract has a different ABI. This is visible by such a [transaction](https://etherscan.io/tx/0x0968b25814221719bf966cf4bbd2de8290ed2ab42c049d451d64e46812d1574e), where the transaction tried to call the method `deposit` (`0xb214faa5`) that does exist on the [deprecated ETH helper smart contract](https://etherscan.io/address/0x7574eB42cA208A4f6960ECCAfDF186D627dCC175) but doesn't on the new contract (it should have been `depositEth` (`0x17c819c4`)). 3. The fix simply consists in reverting the changes regarding the values of the fields `eth_helper_contract_address` and `erc20_helper_contract_address` in `get_minter_info` (so that they point back to [0x7574eB42cA208A4f6960ECCAfDF186D627dCC175](https://etherscan.io/address/0x7574eB42cA208A4f6960ECCAfDF186D627dCC175) and [0x6abDA0438307733FC299e9C229FD3cc074bD8cC0](https://etherscan.io/address/0x6abDA0438307733FC299e9C229FD3cc074bD8cC0), respectively) and adding new fields to contain the state of the log scraping (address and last scraped block number) for the new helper smart contract. --------- Co-authored-by: Thomas Locher <thomas.locher@dfinity.org>

The helper smart contract supporting subaccount is the new preferred way to do deposit, both of ETH and ERC-20. The 2 previous helper smart contracts are therefore deprecated. Concretely,
last_deposit_with_subaccount_scraped_block_numberwas removed. This is not a breaking change since it was never deployed in production.
