Update Drupal core to 8.4.7 via Composer. Security update; I *think* we've
been lucky to get away with this so far, as we don't support self-registration
which seems to be used by the so-called "drupalgeddon 2" attack that 8.4.5
was vulnerable to.

<?php
namespace Consolidation\AnnotatedCommand\Events;

use Consolidation\AnnotatedCommand\Hooks\HookManager;

trait CustomEventAwareTrait
{
    /** var HookManager */
    protected $hookManager;

    /**
     * {@inheritdoc}
     */
    public function setHookManager(HookManager $hookManager)
    {
        $this->hookManager = $hookManager;
    }

    /**
     * {@inheritdoc}
     */
    public function getCustomEventHandlers($eventName)
    {
        if (!$this->hookManager) {
            return [];
        }
        return $this->hookManager->getHook($eventName, HookManager::ON_EVENT);
    }
