Reflective shading surfaces not sensitive to transmittance schedule

Helpdesk ticket 9696
User compares file with reflective shading surface with transmittance schedule always=1.0 to the same file with the shading surface removed. Results should be the same, but the case with the fully transmitting surface shows non-zero reflected solar.

Test files:
Base-ddays-v8.2.idf - with the surface, using ShadowCalculation=AverageOverDaysInFrequency
Evo-ddays-v8.2.idf - without the surface, AverageOverDaysInFrequency
Base-ddays-timestepshading-v8.2.idf - with the surface, TimestepFrequency
Evo-ddays-timestepshading-v8.2.idf - without the surface, TimestepFrequency

The two timesteshading files have a varying transmittance schedule, so the reflected solar should come and go in the Base case, and always be zero in the Evo case. Note that these cases currently crash in v8.2.0 - ref issue #4578

Relevant output variables:
BLOC1:ZONE1_WALL_2_0_0:Surface Outside Face Incident Sky Diffuse Surface Reflected Solar Radiation Rate per Area
BLOC1:ZONE1_WALL_2_0_0:Surface Outside Face Incident Beam To Beam Surface Reflected Solar Radiation Rate per Area
BLOC1:ZONE1_WALL_2_0_0:Surface Outside Face Incident Beam To Diffuse Surface Reflected Solar Radiation Rate per Area

Start by reproducing the behavior with Base-ddays-v8.2.idf, Evo-ddays-v8.2.idf, Base-ddays-timestepshading-v8.2.idf, and Evo-ddays-timestepshading-v8.2.idf, accounting for the crash tracked in issue #4578. Compare the listed reflected-solar output variables; done means a fully transmitting reflective surface matches the case without the surface and timestep-scheduled reflection changes as described.
