Renaming device after setting it as active results in wrong name during interactions

After setting the device as the active device, any of the commands under "Get active device" use the name as it was set when I set it as the active device instead of the new name.

This is a good one! I'll modify the logic to verify that the saved device is still "available" (which would catch both offline and renamed devices) and handle accordingly.
