It can be useful to have a TestWriter that does not log to stdout but stderr instead. For example, that allows for potentially easier filtering of tracing output (because the remaining output of, say, cargo test goes to stdout) or to mirror behavior of env_logger, which by default logs to stderr. Introduce the TestWriter::with_stderr() constructor to enable such usage. The default is left unchanged.

env_logger was doing it, tracing wasn't. Make sure that both do it. Requires tokio-rs/tracing#3187
