Fix obfuscated libs instrumentation (adcolony)

[romtsn]

📜 Description

• Fix another edge-case with obfuscate library (use of uninitialized instance)

Discussed this with Bruno - it's fine to ship it as part of a new 3.1.0-beta.1 (which we anyway wanted to release and promote on wizard to prompt users for auto-installation). Also, to avoid craft issues when releasing from a tag rather than main.

💡 Motivation and Context

Closes #304

💚 How did you test it?

📝 Checklist

• I reviewed the submitted code
• I added tests to verify the changes
• I updated the docs if needed
• No breaking changes

🔮 Next steps

If this happens again we should prioritize #306 over the new issues to unblock users without disabling entire auto-instrumentation.
