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

use Drupal\Component\Render\MarkupInterface;

 * Provides helper methods for assertions.

  /**
   * Casts MarkupInterface objects into strings.
   *
   * @param string|array $value
   *   The value to act on.
   *
   * @return mixed
   *   The input value, with MarkupInterface objects casted to string.

    if ($value instanceof MarkupInterface) {
      $value = (string) $value;
    }
