Previously, `pgroll` could not backfill tables that did not have a primary key or a unique column. From now on, `pgroll` can fallback onto the internal column `_pgroll_needs_backfill` to find all columns that has to be backfilled. I also moved `CNeedsBackfillColumn` constant to the package `backfill` because it makes more sense to have it there. Required by #698
