ThermalStorage:Ice:Simple uses incorrect fluid property in calculation of Delta T

[rraustad]

Issue overview

Code review shows an incorrect use of density where specific heat should be used. In function:

SimpleIceStorageData::CalcIceStorageDischarge

    Real64 CpFluid = FluidProperties::GetDensityGlycol(state,
                                                       state.dataPlnt->PlantLoop(loopNum).FluidName,
                                                       state.dataLoopNodes->Node(this->PltInletNodeNum).Temp,
                                                       state.dataPlnt->PlantLoop(loopNum).FluidIndex,
                                                       RoutineName);

Real64 DeltaTemp = Qice / CpFluid / this->ITSMassFlowRate;
