Rob Findley bb6dadecca mcp: fix cancellation for HTTP transport 
In #202, I added the checkRequest helper to validate incoming requests,
and invoked it in the stremable transports to preemptively reject
invalid HTTP requests, so that a jsonrpc error could be translated to an
HTTP error.

However, this introduced a bug: since cancellation was handled in the
jsonrpc2 layer, we never had to validate it in the mcp layer, and
therefore never added methodInfo. As a result, it was reported as an
invalid request in the http layer.

Add a test, and a fix. The simplest fix was to create stubs that are
placeholders for cancellation.

This was discovered in the course of investigating #285.
