Registry Reset Forgets Half the State

A test fixture resets the registry between tests. After the first test inserts an item, the next test sees a non-empty list and gets an id collision because the counter restarted while the array was not cleared.

Initial failing signallistItems is not empty after resetRegistryExpected listItems() returns [] after resetRegistry and id restarts at 1 · received listItems() returns the previous test's items and id still collides
