snappyHexMesh: Write correct refinement files once only

The files relating to the hex refinement are written out explicitly both by
snappyHexMesh and dynamicRefineFvMesh and hence should be set "NO_WRITE" rather
than "AUTO_WRITE" to avoid writing them twice.  This change corrects the
handling of the "refinementHistory" file which should not be written by
snappyHexMesh.
