Bug fix cht flamelet solver

[EvertBunschoten]

Proposed Changes

The conjugate heat variables were not communicated properly between the flow and flamelet solver, resulting in the interface temperature between the fluid and solid to be always maintained at 300 kelvin for flamelet simulations. The changes mainly regard the recognition of the inclusion of energy for flamelet problems for the CHT methods, while in the flamelet solver, the conjugate variables are obtained from the flow solver instead of the flamelet solver itself.

Related Work

Related work includes the pull requests regarding the flamelet solver, as well as the related regression tests. The latter were obtained with this bug included, so the solution files have to be updated and the residual values in the regression tests have to be updated.
