When guest_console.log is not saved, the test dies in an exception.

Besides the above problem needing more robust handling of opening the file, guest_console.log is saved fine. 

The log file is saved in /tmp/hwcert-$random_directory instead of getting printed on stdout/err of hwcert. This could be improved.
