Prune histogram filter not correctly set in CMPBuild script
Fix: A histogram element is invalid if it has no associated data file
Fix: In rare cases involving manual intervention a prune setting can be altered but not remove any tiles.  In this case a new histogram is calculated which has the same input transform checksum resulting in a duplicate.  This workaround fix removes the duplicate if the original data file does not exist.
