### Motivation This is a temporary revert to fix #3019 while we understand the correct response flow for retried cancelled requests. This PR reverts the behaviour introduced in #2939, which didn't cause problems for NeoVim. ### Implementation I didn't perform a full revert of every single change, since we do want to ensure that we're following the spec. I just stopped returning the error and went back to returning a `nil` response until we figure out what's going on. ### Automated Tests Changed the test so that it asserts the current behaviour. We'll switch it back later.

Motivation
While working on #2938, I noticed that our request cancellation response was incorrect. The spec determines that requests that got cancelled by the client need to return an error using the code for request cancelled (see here and see
RequestCancelledhere).Implementation
Started returning an error with the right code, rather than a response with a
nilbody.I also started running cancel notifications directly in the main thread without pushing it to the queue, which was another mistake. If we put that notification in the queue, then we're guaranteed to only process them after we finish running requests, which is useless. We need the ability to process them as soon as we receive the notification, so that we have enough time to cancel the requests.
Automated Tests
Added a test to verify this.
