This test relies on sending an excessive number of RPC calls via the command line (node.cli('getrpcinfo').send_cli())). I tried sending the RPC calls with node.getrpcinfo() but that does not seem to work, the test keeps running forever.
I could not find a rationale in the original PR for why the CLI is used, but my testing seems to indicate that there is a good reason.
This unbreaks the build-without-cli CI build.
