`website_event_stats_hourly` sets `views` to
`sumIf(1, event_type NOT IN (2, 5))`, so `views` is 0 on custom event
rows and the `events_count` join was summing zeroes. Switched it to
`sum(length(event_name))`, which is how `getWebsiteSessionStats`
already counts custom events on that table.
Also dropped the `getEventExpandedMetrics` change from the previous
commit. That report is filtered to custom events, so every visit it
lists has already fired at least one, and its `bounces` column counts
visits where the event fired exactly once rather than visits with a
single pageview. The threshold rule does not apply there, so the query
is left untouched.
