Race condition in sendRequest in jsonrpc

Lines 1449 to 1450 in fc5ed68

	await messageWriter.write(requestMessage);
	responsePromises.set(id, responsePromise);

In the code linked above, if a response is handled before we get a chance to set the responsePromise on the next line, we will never resolve the request.

The fix should be to set the responsePromise before we await on the message write.

Thanks for the issue and the PR. Release vscode-jsonrpc@8.2.1.

Let me know how it goes.
