Sean Quah 882277008c Fix background updates failing to add unique indexes on receipts (#14453) ... As part of the database migration to support threaded receipts, there is a possible window in between `73/08thread_receipts_non_null.sql.postgres` removing the original unique constraints on `receipts_linearized` and `receipts_graph` and the `reeipts_linearized_unique_index` and `receipts_graph_unique_index` background updates from `72/08thread_receipts.sql` completing where the unique constraints on `receipts_linearized` and `receipts_graph` are missing. Any emulated upserts on these tables must therefore be performed with a lock held, otherwise duplicate rows can end up in the tables when there are concurrent emulated upserts. Fix the missing lock. Note that emulated upserts no longer happen by default on sqlite, since the minimum supported version of sqlite supports native upserts by default now. Finally, clean up any duplicate receipts that may have crept in before trying to create the `receipts_graph_unique_index` and `receipts_linearized_unique_index` unique indexes.
