HiveMetastoreCatalog does not correctly validate partitioned metastore relation when searching the internal table cache

The getCached method of HiveMetastoreCatalog computes pathsInMetastore from the metastore relation's catalog table. This only returns the table base path, which is not correct for non-empty partitioned tables. As a result, cache lookups on non-empty partitioned tables always miss and these relations are always recomputed.
