HVACTemplate:System:VRF doesn't assign a default curve for "Defrost Energy Input Ratio Modifier Function of Temperature Curve" when ReverseCycle is selected

When using the HVACTemplate:System:VRF object and selecting ReverseCycle as "Defrost Strategy", no default curves get assigned to "Defrost Energy Input Ratio Modifier Function of Temperature Curve" of the AirConditioner:VariableRefrigeratnFlow object after ExpandObject runs. The fact that the curve is missing was not triggering a Severe Error in EnergyPlus v8.4 but it does in EnergyPlus v8.5.

Workaround is to used the expidf output file and add an appropriate curve.
