Add checkTxResponse log to RPCResponse (#227)

## Describe your changes and provide context
This change adds back the log string to the `rawLog` of the RPCResponse.

This and sei-protocol/sei-tendermint#125
resolves the following issue:
```
On Cosmos Hub when a tx is broadcast with an incorrect sequence that endpoint will return a successful JSON RPC response with a payload that looks like this:

{"code":32,"codeSpace":"sdk","log":"account sequence mismatch, expected 3, got 4: incorrect account sequence","data":{},"events":[],"gasWanted":0,"gasUsed":0,"hash":{...}}


On the Sei node, when broadcasting a tx with incorrect sequence it returns a JSON RPC error response with an "Internal Error" code:

{"code":-32603,"message":"Internal error","data":"account sequence mismatch, expected 72, got 73: incorrect account sequence"}

```
