Fix incorrect arguments list

This commit fixes the error reported in the forum at https://forum.freecadweb.org/viewtopic.php?f=15&t=33121&start=50#p537787.

This error was introduced when another user replaced the `extractFaceOffset()` method from the PathSurfaceSupport.py module with an improved `getOffsetArea()` function in the PathUtils.py module.  The two instances of the improved `getOffsetArea()` calls here in this fix did not get corrected when that improvement was originally made.
