`pg_class` duplicates `dolt_*` system tables with `dolt_show_system_tables` active.

[NathanGabrielson]

Issue from Prisma integration. On defaults settings doltgres you get the following results:

postgres=> select oid, relname from pg_class where relname like 'dolt_%';
    oid     |          relname

If you set dolt_show_system_tables to 1, you get the following, which seems to be tripled and then with a couple more tables?

select oid, relname from pg_class where relname like 'dolt_%';
    oid     |          relname
