Correctly reschedule already updated feeds
Correctly reschedule already updated feeds

If we request to update a feed that was just updated, previously we would
zero out the next update time (thus forcing it into a loop of updates)
because the next update wasn't set. Now, set it normally so that it is
correctly in the future.
