Fix partitioned index attachment
When an existing index in a partition is attached to a new index on its parent, we forgot to set the "relispartition" flag correctly, which meant that it was not possible to find the index in various operations, such as adding a foreign key constraint that references that partitioned table. One of four places that was assigning the parent index was forgetting to do that, so fix by shifting responsibility of updating the flag to the routine that changes the parent.
