Fix bug in debugfs logs that causes an incorrect order of lines in the debugfs log.
Currently, any suite diagnostic lines, including the test counts lines that show the number of tests passed, failed, and skipped, appear prior to the individual results, which is a bug.
Ensure the order of printing for the debugfs log is correct.
