TUT: faSchemes: replace snGradSchemes with lnGradSchemes (fixes #2543)

When a finite-area case could not find an entry for "lnGradSchemes"
in the "faSchemes" file, the "corrected" scheme has been picked up
by default. Therefore, any changes in "snGradSchemes" entry will not
be read by finite-area models.
