Fix regression testing false negative - #3255

The QoR parsing script returned -1 in case of a mismatch between arch file name in the actual run and the golden results. If there was 1 run failures, the -1 would cancel the 1 and as a result the regression tests would pass while having errors. This commit fixes that by not throwing an exception in that specific case (Therefore not returning -1) and taking the absolute value of the QoR and run failures.

Just to add, the only reason all the strong tests were actually ran in the linked CI run was that the scatter gather tests were at the end of the task list. If you moved it to the beginning, the script would crash at the start, no other tasks would be run, and CI would've still passed. |

The test has passed the CI but there are actually errors:

Why did it pass? Well there this piece of code:

But that's not the root cause. The QoR parsing script returned -1 in case of a mismatch between arch file name in the actual run and the golden results. In case of 1 run failure, the -1 would cancel the 1 and as a result the regression tests would pass while having errors. This commit fixes that by not throwing an exception in that specific case (Therefore not returning -1) and taking the absolute value of the QoR and run failures before summing them up.
