ATTACH PARTITION: Don't match a PK with a UNIQUE constraint When matching constraints in AttachPartitionEnsureIndexes() we weren't testing the constraint type, which could make a UNIQUE key lacking a not-null constraint incorrectly satisfy a primary key requirement. Fix this by testing that the constraint types match. (Other possible mismatches are verified by comparing index properties.)
