The error/warning logs that appear in integration test is pretty annoying

[KSXGitHub]

The test logs does not show them before due to miniserve's logs being disabled by default. But now they are shown alongside normal test logs makes it hard to read the logs that actually matters.

Suggestion

Do not redirect stderr output of subprocess to parent's stderr.

P.S. I am not familiar with std::process so I am going to waiting for someone else to do it.

I didn't notice this before but I entirely agree. This is annoying to read.
