[Users] parsing bug for temperature_evolution_method

Dear all,

I have encountered a bug in using HydroBase::temperature_evolution_method. If it is given explicitly by taking its default value "GRHydro", my runs crashed while reading a Lorene data. But if it's not given in the parameter file, it run smoothly but the results are the same with the case of taking "none".

I found this bug when I was testing Hybrid EOS. I've tried to realize pure Polytrope (or Ideal_Fluid) by using the piecewise Hybrid EOS interface. But the results are showing around 10% more variations in rhomax compared to the pure Polytrope/Ideal_Fluid cases.

I'm using Turing version. Thanks for you help in advance.
