/**
* The `assertThatAndTurbinesConsumed` function ensures that the assertion passed and
* all events in the given turbines have been consumed.
*
* Usage:
* val actualValue: T = getActualValue()
* val turbines: List<ReceiveTurbine<*>> = getTurbines()
* assertThatAndEnsureAllEventsConsumed(actualValue, turbines) {
* // your assertion here
* }
*
* @param T The type of the actual value.
* @param actual The actual value being asserted.
* @param turbines The list of ReceiveTurbine instances to check if all events are consumed.
* @param assertion An extension function on `Assert<T>`, which is used to define assertions on the actual value.
