fix(cctv): warn once per failed background refresh; test the single flight

Browse Source 
Attach the background-refresh warning where the refresh starts, so a
failed refresh logs once instead of once per request served meanwhile.
The test now checks that requests during a refresh share it, and turns
the hang off before releasing the fetches so a retrying loader can't
stall it.
