Failed outbounds not properly removed from ethereum (and evm?) signer cache

Example Inbound: https://thornode-v1.ninerealms.com/thorchain/tx/details/3CB3935B2C75707D954884ED251E10B6F568AF2CAA4283E6695E8E2F15D25D75 Outbound: https://etherscan.io/tx/0x563e3585278695650fde16ac31adc262b1b63bebd1c39c08a3dcee0dcd28d1e4

The upstream issue was #1796 (closed) and this particular case should be avoided with that resolution, but we should still ensure the failed outbound is removed from signer cache. It would seem https://gitlab.com/thorchain/thornode/-/blob/v1.126.0/bifrost/pkg/chainclients/ethereum/ethereum_block_scanner.go?ref_type=tags#L854 should do this, however it does not and there is no corresponding information in the logs.

Relevant logs from signer filtering for this outbound:
