Rosetta empty error responses to not queryable blocks

[JulianToledano]

Summary of Bug

Currently calling to /block with a height of a block that is not queryable results in an empty error:

{
  "code": 0,
  "message": "unknown",
  "description": "unknown error",
  "retriable": false,
  "details": {
    "info": "rosetta: (0) unknown"
  }
}

This is because right now only cosmos-sdk/tools/rosetta/lib/errors are being parsed to rosetta errors.

Version

61effe8

Steps to Reproduce

Start rosetta server:

simd rosetta --blockchain Cosmos --network cosmoshub-4 --grpc $GRPC:9090 --tendermint $TENDERMINT:26657 --log_level debug

get the current_block_identifier from /network/status

curl  localhost:8080/network/status -d '{"network_identifier":{"blockchain":"Cosmos", "network":"cosmoshub-4"}}' | jq

{
  "current_block_identifier": {
    "index": 13060921,
    "hash": "D9528ED4B886E5677C7BB90E95B04EE355282F4F08F02B4E14143FA38D271B00"
  },
  ...

make a request to /block with a higher current_block_identifier.index

curl  localhost:8080/block -d '{"network_identifier":{"blockchain":"Cosmos", "network":"cosmoshub-4"},"block_identifier":{"index":13060930}}' | jq

Proposal

Wrap also jsonrpc errors from tendermint to rosetta:

// ToRosetta attempts to converting an error into a rosetta
// error, if the error cannot be converted it will be parsed as unknown
func ToRosetta(err error) *types.Error {
	switch err := err.(type) {
	case *Error:
		return err.rosErr
	case *tmtypes.RPCError:
		return fromTendermintToRosettaError(err).rosErr
	default:
		return ToRosetta(WrapError(ErrUnknown, ErrUnknown.Error()))
	}
}

func fromTendermintToRosettaError(err *tmtypes.RPCError) *Error {
	return &Error{rosErr: &types.Error{
		Code:    int32(err.Code),
		Message: err.Message,
		Details: map[string]interface{}{
			"info": err.Data,
		},
	}}
}

will result in:

{
  "code": -32603,
  "message": "Internal error",
  "retriable": false,
  "details": {
    "info": "height 13060930 must be less than or equal to the current blockchain height 13060921"
  }
}
