When using sendAsync, the payload parameter may contain an existing object id. I've added a check for if the id is set and to use it instead of generating a new id.

Why should caller ever be responsible for setting id?

@moodysalem It's because web3js pub sub likes to generate its own IDs for sendAsync actions so it knows which message is the rpc response. It's a weird use-case, but it's needed.

): Promise<
| JsonRpcSucessfulResponseMessage<TResult>
| JsonRpcErrorResponseMessage<TErrorData>
> {
const id = getUniqueId();
const id = Number.isNaN(optionalId as any)

Here we should check for undefined values, if optionalId value is undefined then id will be undefined too

This fix solve an issue that I have when send rpc messages from my app (inside iframe) to metamask:
Wrong response id "3610003435135761" (expected: "13") in {"jsonrpc":"2.0","id":13,"method":"eth_getBlockByNumber","params":["latest",false]}
