AirloopHVAC:UnitarySystem shows different heating capacity than heating coil #9105

Issue overview

Example file UnitarySystem_DXCoilSystemAuto shows incorrect sizing of downstream heating coil. This example file uses 2 unitary systems, one with a cooling coil upstream of the other which has a heating coil. With these systems in the same air loop the original intent was to size the coils with the same capacity. This is partially working, however, the upstream UnitarySystem reports the autosized (independent of the upstream system coil) capacity while the heating coil reports the same as the upstream cooling coil.
