kinematicParcelFoam -postProcess tries to load surfaceFilmProperties always

Summary

All solvers with kinematic parcels when in -postProcess mode try to load surfaceFilmProperties even if `surfaceFilmModel none'.

Steps to reproduce

Run tutorials/lagrangian/kinematicParcelFoam/spinningDisk with kinematicParcelFoam -postProcess

What is the current bug behaviour?

Tries to load surfaceFilmProperties

What is the expected correct behavior?

Not load anything since is not used.

Possible fixes

regionModels/surfaceFilmModels/surfaceFilmModel/surfaceFilmModelNew.C does a MUST_READ. Could be READ_IF_PRESENT?
