OCI: Match the constraints on the index_name column

Browse Source 
When looking for the primary index, it is possible that the
constraint_name in the all_ind_columns table does not match that of the
index_name. Whereas the index_name will match in this case, so the query
should set the where clause on the index_name in both tables.
