Refactor database queries and error handling in multiple artifact scripts

[rafaeljonathannh]

Summary

This PR hardens multiple parsers against schema variations, missing tables, malformed files, and uninitialized variables. The goal: remove all crash paths caused by unexpected DB structures or corrupt input.

---

Changes

notificationHistory.py

• Short-circuit XML parsing before ParseFromString to avoid attempting to parse raw XML.
• Added guard for parse failures; corrupted XML files are now skipped instead of crashing.
• Fixes "Unexpected end-group tag" error.

gmailEmails.py

• Initialize messagehtml for every row prior to use.
• Eliminates UnboundLocalError when email rows lack HTML parts.

googleMapsGmm.py

• Verify sync_item table exists before running queries.
• Log and skip gracefully when absent.

googleDuo.py

• Queries made schema-aware: do not rely on missing columns (self_id, call_state, outgoing, content_size_bytes, saved_status).
• Add fallbacks to empty values when columns are absent.
• Wrap all queries with existence guards to avoid OperationalErrors.

googleMessages.py

• Schema-aware attachment handling:

  • Use file_size_bytes / local_cache_path when present.
  • Fall back to storage_uri / uri, or empty when all missing.

• Guard all attachment queries from missing-column crashes.

wireMessenger.py

• Robust join between assets and messages:

  • Detect presence of Assets2, Assets, asset_id, _id dynamically.
  • Fall back to available identifiers instead of crashing.

• Fixed indentation issues and prevented missing-column exceptions.

wellbeing.py

• Check presence of component_events table before querying.
• Log and skip instead of raising "no such table" errors.

---

Outcome

• All previously reproducible crashes/OperationalErrors caused by DB schema variation have been eliminated.
• Parsers now fail gracefully: skip malformed or incompatible data instead of aborting the entire run.
• Fixed one case of uninitialized variable (messagehtml).
• Overall robustness and portability across different Android app versions significantly improved.

---

Testing

• Verified all modified modules run on:

  • Full datasets with complete schemas.
  • Minimal datasets missing various tables/columns.
  • Corrupted / partial XML or DB files.

• Confirmed zero crashes across tests; all failures logged and skipped as intended.

---

Checklist

• No more OperationalErrors
• Handles missing tables/columns cleanly
• Logs failures instead of raising
• Backwards-compatible
• Ready for merge
