    Swap the order of stdout and stderr in debug output

    Generally this data is looked at because something failed, and in
    that case the relevant error is likely to be at the end of stderr.
    By concatenating the output stderr first and then stdout as we were
    it is possible for the stderr to get lost entirely in the failures
    list, and even if that doesn't happen it's best to output the
    relevant error right at the end of the output where people will
    see it. Previously it would be buried in the middle of the debug
    output.
