mechanism to handle dropped events due to ShouldBeUnique

[travisghansen]

In Illuminate\Foundation\Bus\PendingDispatch can we expand the __destruct() function to allow handling when jobs are dropped? Below is an example adding a check for a droppedDispatch method on the Job and invoking that when dropped.

    /**
     * Handle the object's destruction.
     *
     * @return void
     */
    public function __destruct()
    {
      if (! $this->shouldDispatch()) {
            if ($this->job instanceof ShouldBeUnique && method_exists($this->job, 'droppedDispatch')) {
                $this->job->droppedDispatch();
            }
            return;
        } elseif ($this->afterResponse) {
            app(Dispatcher::class)->dispatchAfterResponse($this->job);
        } else {
            app(Dispatcher::class)->dispatch($this->job);
        }
    }
