FIX: migrations must be finished to reset flags cache (#29693)

Browse Source 
Bug introduced here: https://github.com/discourse/discourse/pull/29609

It was checking if `flags` table existed before resetting the cache. However, `require_message` flag was added in further migration:

https://github.com/discourse/discourse/blob/main/db/migrate/20240714231226_duplicate_flags_custom_type_to_require_message.rb#L5

When the admin tried to update Discourse which already has `flags` table but no `require_message` column, it was causing the error.

Therefore, we should ensure that all migrations are finished before resetting flags cache.
