Fixed SQLite purges with world and block filters purging other tables (#1025)

On SQLite, /co purge r:#world i:<block> built the retain condition for
world-scoped tables without checking the block restriction, so it purged
co_container, co_chat and the other world-scoped tables in that world
although a block restriction should leave them untouched. The
entity_container/entity_interaction branch and the MySQL path already
check it.
