shutdown result is non-null

Description

In response to a shutdown request, the server responds with:

{"jsonrpc":"2.0","id":2,"result":{}}

That result of {} doesn't match the specification, which indices that the result should be null.

This really isn't that big a deal, but we found it, and figured it was worth reporting.

Steps to Reproduce

send a shutdown request

Logging

No response
