Test logs sometimes contain color codes

This doesn't happen with all tests, but I've seen it happen with "dotty1$1".

I can't reproduce this - can you do this post #2248?

You can reproduce it by running tastyBootstrap, if you look at the options passed to tastyBootstrap#dotty1 you'll see that they don't include the option to disable colors.
