Spread runner CI minute reset to 8 hours

See merge request gitlab-org/gitlab!50265

Due to how HLLRedisCounter#weekly_redis_keys converts
dates to calendar week, it would result in an empty
array when the calendar week of end_date occurs before
the calendar week of start_date.

For example, given start_date 2020-12-01 and
end_date 2021-01-01, the calendar week would be reversed,
resulting in empty array from #weekly_redis_keys

Previously when group issues were queried, we called a SELECT for each
project and its associated project features to check whether the user
had permission to read the issue. We now solve this by preloading those
items unconditionally.

The `apply_lookahead` defines a method `preloads` but redefines this
method as a local variable. Rename the local variable to avoid
confusion.
