Once in a while, in release mode only, this test will display this symptom: ``` ... record_id=163 severity=trace time="2023-Oct-03 16:22:53.911616" name="http_client" url="http://127.0.0.1:8001" msg="Read 16384 bytes of body data from stream." record_id=164 severity=trace time="2023-Oct-03 16:22:53.911802" name="http_client" url="http://127.0.0.1:8001" msg="Read 16384 bytes of body data from stream." record_id=165 severity=warning time="2023-Oct-03 16:22:53.912043" name="http_client" url="http://127.0.0.1:8001" msg="Client destroyed while request is still active!"

But although the root cause isn't known, it's believed to happen when the body has not been completely consumed, and the program exits. Since this "don't-consume -> then exit" scenario is very unlikely in production, work around it by making sure both handlers have run before exiting, instead of only one of them. I tested this for hundreds of runs, and it worked. Previously it would fail every 15-30 runs or so. This also has the added benefit of not accidentally skipping the test conditionals inside the body handler. Signed-off-by: Kristian Amlie <kristian.amlie@northern.tech>
