NM CI failures. When invoking nmcli, libnm reports a warning: libnm-WARNING **: No object known for /org/freedesktop/NetworkManager/Devices/15 This fools the test checks, making it fail.
basically the same as bug 1457223.
Test fixed dropping stderr on the test checks (so ignoring the libnm warning). Closing as NOTABUG as from a functional PoV the test was successful, was just the warning that mangled the parsing of the check output. Living libnm warnings to be addressed in: https://bugzilla.redhat.com/show_bug.cgi?id=1457223.
