Material:RoofVegetation with anything other than CTF should be fatal.

[mjwitte]

Issue overview

A user file with Material:Roofvegetation and HeatBalanceAlgorithm ConductionFiniteDifference results in unrealistic roof surface temperatures.

Looking at output variable BLOCK1:ZONE1_ROOF_1_0_0:CondFD Surface Temperature Node 1 [C](Hourly), with v9.4 it shows very high temperatures (>300C), and with v25.1-9c7c2a6d79, that node reports 0C all year.

There is a severe error message, but this should terminate the simulation since it produces garbage results.
** Severe ** CalcEcoRoof: EcoRoof simulation but HeatBalanceAlgorithm is not ConductionTransferFunction(CTF). EcoRoof model currently works only with CTF heat balance solution algorithm.

1. Fatal out for this condition.
2. Make sure this works ok if the file uses SurfaceProperty:HeatTransferAlgorithm or SurfaceProperty:HeatTransferAlgorithm:MultipleSurface.
