Multiple errors in flaky test create_and_destroy

Flaky tests were detected in [this test run](https://github.com/cmss13-devs/cmss13/actions/runs/22706271951/attempts/1). This means that there was a failure that was cleared when the tests were simply restarted.
Failures:
```
create_and_destroy: /obj/item/device/flashlight/flare/signal/debug hard deleted 1 times out of a total del count of 2 at code/defines/../modules/unit_tests/create_and_destroy.dm:140
create_and_destroy: /obj/structure/machinery/colony_floodlight_switch hard deleted 1 times out of a total del count of 2 at code/defines/../modules/unit_tests/create_and_destroy.dm:140
create_and_destroy: /obj/structure/machinery/colony_floodlight_switch/electrified_fence_switch hard deleted 1 times out of a total del count of 2 at code/defines/../modules/unit_tests/create_and_destroy.dm:140
```

Start with code/modules/unit_tests/create_and_destroy.dm around line 140 and inspect the linked GitHub Actions run for the failure context. Reproduce the test and trace the lifecycle of the three listed object paths. Done means the test no longer reports hard deletions for these objects across repeated runs.
