Remove all tests as they depend on FilterDesktop

FilterDesktop is being removed as part of Rec#358 . =HltIntegrationTests= depends on it and hence it is removed. Please fix and re-add in a separate MR if it still serves a purpose. The project https://gitlab.cern.ch/lhcb/LHCbIntegrationTests (see Davide's talk) could be a better place.

Eventually Rec#358 will lead to the removal of DaVinciAlgorithm and thus DecayTreeTuple. This will make MooreAnalysis an empty shell. I suggest to terminate this project asap (not first time I say that 😉).
