eth/tracers/call: Fix call_tracer withLog == true && onlyTopCall == true

[andreisilviudragnea]

Fixed missing logs for callTracer calls having withLog == true && onlyTopCall == true:

curl --location 'http://0.0.0.0:8545' \
--header 'Content-Type: application/json' \
--data '{
    "jsonrpc": "2.0",
    "method": "debug_traceTransaction",
    "params": [
        "0x506d0ce623a33ef868780a99f051b5eba5c82fc5dd2826ee1bb0b666131a6fb8",
        {
            "tracer": "callTracer",
            "tracerConfig": {
                "withLog": true,
                "onlyTopCall": true
            }
        }
    ],
    "id": 1234
}'

So the expected response is:

{
    "jsonrpc": "2.0",
    "id": 1234,
    "result": {
        "from": "0x82211934c340b29561381392348d48413e15adc8",

        "logs": [
            {
                "address": "0x83e32b17b3a5fee7ea3294bca3840f54818edf92",

                ],
                "data": "0x00000000000000000000000000000000000000000000000000000000000000400000000000000000000000009f333fc2a4b329addb8e0b5ac34653b53c79c264000000000000000000000000000000000000000000000000000000000000003043616c6c6572436f6e7472616374322066756e6374696f6e2063616c6c656420616e6f7468657220636f6e747261637400000000000000000000000000000000",
                "position": "0x0"
            }
        ],
        "value": "0x0",
        "type": "CALL"
    }
}

The depth parameter of func (t *callTracer) CaptureState(pc uint64, op vm.OpCode, gas, cost uint64, scope *vm.ScopeContext, rData []byte, depth int, err error) is 1 for root EVM in a transaction, not 0.

Looks correct to me. We increment the depth first in EVMInterpreter.Run before CaptureState is called.

Good catch!
