In the BE we build partition names with the trailing char '/'. In the FE we build partition names without a trailing char. We should make this consistent because this causes some annoying string adjustments in the FE and can cause hidden bugs. This patch creates partition names without the trailing '/' both in the BE and the FE. This follows Hive's behavior that also prints partition names without the trailing '/'.
