Fix the bug of showing '1/1' of 'Subtest Pass Rate' when the result of the reftest(or manual test) is not 'PASS'.

I'm very sorry for dropping PR1008 which James Graham also reviewed.
Thanks to James Graham. 
For my wrong git operation, I find the code of pull request1008 would be not update while I have modified trailing whitespace James suggested on my own branch. 
So I dropped PR1008 and repull new request.
