## Description generates a unique repository ID on repo init, and retrieves it again on repo connect. This allows the event bus (and any other tracker) to id a repo independent of other context. I've been unable to find any good way to retrieve a unique repository ID from kopia. This seems like the next quickest solution. ## Type of change - [x] 🐛 Bugfix ## Issue(s) * #1602 ## Test Plan - [x] 💪 Manual
