Add test for issue #17: verify get-documents works without limit/offset parameters

- Test confirms that get-documents works when limit/offset are not provided
- Validates that default values (offset=0, limit=20) are applied correctly
- Ensures no None parameter errors occur (issue #17)
- Focused test with minimal scope for the specific issue

Closes #17
