Loader: Renaming an addon will cause duplicate detection race condition.

[DeltaGW2]

Restart the game as a workaround.

Developer notes:
This is because the first addon is being unloaded async.
So when the “new” addon gets loaded, the old one is still loaded → Duplicate.

Possible solution:
Check first → No longer exists → State = None → Reload the other to consume the original addon.
