fix(expo-web): Multiple Debug IDs can be loaded into the global polyfill

[krystofwoldrich]

📢 Type of change

• Bugfix

📜 Description

Expo SDK 50 with React Router can use bundle splitting on the web.

Our RN Debug ID polyfill always created an empty Debug ID carrier when invoked. This deleted previously loaded Debug IDs.

• fixes expo web not sending debug ids - metro #3638
