Fixes #27

Description

• Given this drizzle.config.ts

export default defineConfig({
  schema: `db/schemas`,
});

• And this folder struct:

└── schemas
    ├── index.ts
    ├── posts.ts
    └── users.ts

• Whith barrel export of schemas in index.

When extracting Drizzle objects, we had duplicates (from index and from the other files in /schemas, captured by the glob defined in the config.schema).
