Fix a bug on Calendar event day views for all day events in certain timezones

Summary:
Ref T11816. This logic was correct, we just did all the work and then mostly threw away the results. This worked correctly anyway in some timezones.

Instead, actually use `$min_date` and `$max_date`.

Test Plan: In "America/Toronto" with server in a more-western timezone, viewed a "Nov 11 - Nov 12" all-day event, saw those dates.
