This juju bug https://bugs.launchpad.net/juju-core/+bug/1576509
shows that reading after a request has returned, which
http.Client.Do can (see Go issue golang/go#12796) is a problem.
Ensure that DoWithBody can never do that by closing
the existing readStopper body which is in place for
just that reason.
