[native] Remove dangling device after QR auth failure

Summary:
Address ENG-10309.
Try reverting device list update after the process failed at a later point.

Test Plan:

1. Replaced await sendDeviceListUpdateSuccessMessage() with throw new Error('foo')
2. After alert is shown, verified that:
   • No new device is present on the Linked Devices screen
   • Checked DynamoDB - two device list updates are present: the first update added a new device and the second update removed it. Before this diff, only the former update was present, resulting in dangling device on the list.
