Removed unused import that was causing CI lint failure

- Removed assertions for packages getter (not available in v7) - Removed assertion for enableTracing property (removed in v7) - Added comments explaining the API changes

The method was a no-op after v7 API changes, so removing it entirely to avoid unused parameter warnings from PMD.

The file is in the parent directory, so use ../ prefix to fix the import path

The property is deprecated in v7. Tracing is already disabled by setting tracesSampleRate and tracesSampler to nil.
