cue: make the tests non-chatty by default

Marcel's various debugging TestX tests do turn on verbose logging
in the evaluator always, but regular tests which run by default
should not print hundreds of debugging lines to stderr.

Just in case Marcel needs to re-enable this again soon,
leave the lines commented out, as they're not harmful this way.
