eth_getCode returning 0x0 instead of 0x for non-contract addresses

[tom-hbar]

Description

When making a request using the eth_getCode method for a non-contract address, the result value returned is 0x0. Other relays (such as Ethereum or BSC relays) return 0x. This can cause issues if applications or libraries are expecting 0x but not 0x0.

It might be worth modifying the result value to return 0x to cover applications or libraries that do not expect 0x0, especially if this is standard for relays on other chains.

Steps to reproduce

1. Make a request to the JSON RPC relay with the eth_getCode method for a non-contract address

curl -X POST -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0","id":"2","method":"eth_getCode","params":["0x0000000000000000000000000000000000000000", "latest"]}' https://testnet.hashio.io/api

Response received:
{"result":"0x0","jsonrpc":"2.0","id":"2"}

Response expected:
{"result":"0x","jsonrpc":"2.0","id":"2"}
