better logging in case of jsonrpc errors

[iuwqyir]

TL;DR

Improved error logging for nil block results in the RPC serializer.

What changed?

Enhanced the error handling in SerializeFullBlocks function by:

1. Including the original error from rawBlock.Error in the log message
2. Adding the original error details to the error message returned in the result

How to test?

1. Trigger a scenario where a nil block result is returned from an RPC call
2. Verify that the logs now include the original error information
3. Confirm that the error message in the result contains the details from the original error

Why make this change?

This change provides more detailed error information when nil block results are encountered, making it easier to diagnose issues with RPC calls. The previous implementation only logged that a nil result was received without including the underlying error details, which limited troubleshooting capabilities.
