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.)
