./run_nyx shows stem's debug output

[traumschule]

I did not find out why I see stem's debug output with ./run_nyx from a fresh clone:

nyx_fresh$ ./run_nyx -d nyx.log

Hi traumschule, sorry about letting this languish so long! Back on #27350 this pretty thoroughly confused me and I gotta admit, I'm still puzzled. I've tried a few different things to reproduce this but no luck.

Per chance have you modified Stem or Nyx at all? This certainly looks like we've called Stem's log_to_stdout() helper but that's never done within Nyx.

If you're certain Stem and Nyx are unmodified please double check that this issue reproduces with the latest git commits of Stem and Nyx, and provide your torrc and I'll try again with that.
