dev/core#3804 - Fix recently performed activities on case dashboard when no upcoming exist

[demeritcowboy]

Overview

This is the same as #24261 but is a reviewer's cut with the added test and requested changes.

https://lab.civicrm.org/dev/core/-/issues/3804

Before

1. Make sure there are no upcoming case activities. One way to do this is create a backdated case with a start date 2 years ago, then change the status of any scheduled ones to completed.
2. Create a recent case activity, e.g. backdate it 2 days and mark it completed.
3. Visit the case dashboard. Note it does not show the recent activity.

Unit test fails with Failed asserting that '0' matches expected 1.
