updated reference results for heat pumps
added electrical power output to heat pump reference results
updated reference results for models with a relative error smaller than 5e-4. One model had a larger error but this is caused by the changed implementation of a temperature sensor around zero flow
Renamed unit test PumpWithPipeHeatPort  so its name is not equal to the test in the pump example package.
Added reference result.
updated reference results for PumpWithPipeHeatPorts example
added more reference results for failed simulations of unit tests
fixed some models that accidentally used blocks from Buildings library instead of MSL
