Disable tracing-subscriber default features in tracing-test?

[eric-seppanen]

Would it be possible to add default-features = false to the tracing-subscriber dependency? It would be nice to not override the end-user's attempt at disabling features.

I found out this was a problem when I added a unit test using tracing-test and the next time I deployed my server the logs are full of ansi color sequences because the tracing-subscriber default features include ansi color output. :)
