fix: reduce time and increase reliability of tests

[salonig23]

Ticket

Description

This test has been quite flaky and times out quite often. Steps taken to increase reliability:

• Reduced the time incremented by fake clock in each test
• Moved time to just after midnight instead of midnight on the dot to avoid syncronization issues
• Reduced the default log retention days.

Test Plan

Ran each test locally a 100 times. The average time of each tests are:

• TestScheduleRetentionNoConfig: 0.71s
• TestScheduleRetention100Days: 1.79s
• TestScheduleRetentionNeverExpire: 5.07s

Checklist

• Changes have been manually QA'd
• User-facing API changes need the "User-facing API Change" label.
• Release notes should be added as a separate file under docs/release-notes/.
  See Release Note for details.
• Licenses should be included for new code which was copied and/or modified from any external code.
