Import thermal conductivity fails on ThermalSinglePhaseFluid

[behzaadh]

Importing thermal conductivity through vtu file does not work even though I get successful messages using ThermalCompressibleSinglePhaseFluid model.

To Reproduce
use the ThermalCompressibleSinglePhaseFluid model and try to import SinglePhaseThermalConductivity using vtu file. You would see the values in the output files are similar to the xml file not the vtu file.

Additional context
I looked at the source code and realized that in the SinglePhaseThermalConductivity class and the initializeRockFluidState function, you are overwriting the default values on the vtu data.
