A failing YouTube feed is asked again hourly for a day (#386)

Browse Source 
#382's retries run (each failing fetch takes the two seconds) and still
end 404: YouTube fails about 70% of feed reads from Tower, in streaks
longer than seconds, for ?user= and ?channel_id= addresses alike (142
and 68 failures in 7 days across 26 and 13 feeds). The 39 YouTube
channels are catalogue feeds nobody subscribes to, read once a day, so
each missed about 5 days in 7.

due_at now waits at most an hour for a YouTube feed in the first day of
a run of failures. A channel gone for good costs 24 requests, then backs
off as any feed does.
