## Description
ref: #10968
In case of MsgExec failure, we added a `logs` field in the event. While debugging #11679, I noticed these logs were not clear.
Before, the event on MsgExec failure looks like:
```

}
```
After, it looks like:
```
{
"key": "logs",
"value": "\"proposal execution failed on proposal 2, because of error message /cosmos.bank.v1beta1.MsgSend at position 0: 0stake is smaller than 10stake: insufficient funds\"",
"index": true
}
```
