// Tests a case when `done_callback` resets the `barrier_callback`.
// `barrier_callback` is a RepeatingCallback holding the `done_callback`.
// `done_callback` holds a reference back to the `barrier_callback`. When
// `barrier_callback` is Run() it calls `done_callback` which erases the
// `barrier_callback` while still inside of its Run(). The Run() implementation
// (in base::BarrierCallback) must not try use itself after executing
// ResetBarrierCallback() or this test would crash inside Run().
