Re-enable Graph tests (#3287)

Although the Graph module was deprecated, we want to have tests running
as long as we keep the client code. Therefore re-enable the Graph tests, by
adding to the docker-compose stack an older redis-stack-server image. The
Graph tests run only with RESP2.

Tweak the CI so that it runs against the latest RC release for now. This way
we get all the features in RC release of server, so we can execute all tests,
including the ones for hash field expiration.

Some test failures brought to light issues with the RESP3 push message
invalidation handler, align a bit the code in that area.

Some more housekeeping around tests, here and there.
