test(cli): hand a config command's session flags to the daemon

cli_with_config passed every flag to the client, so in daemon mode the
wishlist serve tests started their daemons with no --shared-dir. Those
daemons fell back to sharing ~/Downloads/Soulseek, and the tests only
passed because an earlier download test happened to create that folder;
run alone, shuffled, or on a machine without it, both failed with
"nothing to share". Session flags now go to the daemon the way cli()
already routes them.
