Worker metrics PAvgQPS and AvgQPS are unnecessarily divided by 1000000

[nck-mlcnv]

The following data contains 2 tasks with each having one worker. The expected result should be, that each worker metric result is equal to the coresponding task metric result (as there is only one worker per task). The result is created with the version 3.3.3. The bug probably has something to do with #224, as the metric tests ran fine with the previous version before the PR.
