internal/daemon/worker: improve runtime and reduce noise

TestRotationTicking would previously wait for 5 rotations, which is
pretty slow considering each rotation takes 20 seconds. Reduce
the number to 3, and use require instead of assert to remove
noise during flaky test runs.

This doesn't fix the flakiness of this test, but it should reduce the log spam.
