Fix jsonrpc payload and response types (#4743)

* Make JsonRpcPayload's `params` field optional

Currently jsonrpc.js uses `params: params || []` in the
`toPayload` function, so this type update makes the `params` field
optional to match.

* Fix JsonRpcResponse type

Update `id` to accept `string | number` - this now matches the
`isValidResponse` function in `jsonrpc.js`.

Update `error` to accept an object with optional `code`, `data`,
and non-optional `message` fields to more closely match the
[JSON RPC spec](https://www.jsonrpc.org/specification#error_object)
and the `ErrorResponse` function in `errors.js`.

* Remove errant spaces

* Add PR #443 to CHANGELOG
