Remove PIPE arg and make QuiteHandler the default

Passing a pipe to the subprocess, but not reading from it
conceals helpful error messages.
As the code redirects all of the stderr from the subprocess
to nowhere, the error output of the process is never read.
If we remove the PIPEs from the tests we should see some
error messages on the console/logger that can
help us understand what went wrong.

On another hand, when we stop passing stderr=subprocess.PIPE arg
to the subprocess.Popen function call there are a lot of
HTTP messages together with the helpful error messages.
One decision is to make QuietHTTPRequestHandler
the default. That way we receive the helpful error messages
without the HTTP messages.
