Merge pull request #2729 to Fix library reaction barrier heights for linear scaling.

If you include a library for a surface mechanism that uses linear scaling, this can cause some reaction barriers to be below the endothermicity of the reaction. This PR fixes the barrier heights for library reactions that have been scaled across metals
