Fix issue with Pixel han-config due to non-supported DQ algorithms

In the last DQWebDisplays we observed some missing histograms for Pixel, e.g.:

https://atlasdqm.cern.ch/webdisplay/tier0/1/physics_Main/run_450227/run/InnerDetector/Pixel/BLayer/Hits/AvgOccActivePerLumi_BLayer

this was traced back to an issue with the Pixel han-config file using DQAlgorithms not supported anymore. This MR is fixing this issue. Test display has also been created here:

https://atlasdqm.cern.ch/webdisplay/test/9997/physics_Main/run_450227/run/InnerDetector/Pixel/BLayer/ClusterHits/ClustersPerLumi_BLayer

to show that the correct behavior has been restored
