Problem/Motivation

Error:

TypeError: Symfony\Component\Mime\Header\Headers::addTextHeader(): Argument #2 ($value) must be of type string, null given, called in /var/www/html/vendor/symfony/mime/Header/Headers.php on line 152 in Symfony\Component\Mime\Header\Headers->addTextHeader() (line 122 of /var/www/html/vendor/symfony/mime/Header/Headers.php).

When sends a message with Bcc, and without to, on the version 2.2.x it fills the to with a string.
https://git.drupalcode.org/project/reroute_email/-/blob/c61b4e654687d902...

  $mailkey = $message['id'] ?? t('[mail id] is missing');
  $to = $message['to'] ?? t('[to] is missing');

But on the version 2.3.x it expected a string, and never a NULL.
https://git.drupalcode.org/project/reroute_email/-/blob/a45e1158adf0e868...

  /**
   * {@inheritdoc}
   */
  public function getAddressTo() {
    if (array_key_exists("to", $this->configuration["email"])) {
      return $this->configuration["email"]["to"];
    }
    return NULL;
  }

On the method getAddressTo, returns NULL, because Symfony mailer set it the to, to NULL, see issue https://www.drupal.org/project/symfony_mailer/issues/3281130 →

But, the method setHeader expects a string.
https://git.drupalcode.org/project/reroute_email/-/blob/a45e1158adf0e868...

    $this->setHeader(RerouteEmailHandlerPluginInterface::HEADER_ORIGINAL_TO, $this->getAddressTo());

https://git.drupalcode.org/project/reroute_email/-/blob/a45e1158adf0e868...

  /**
   * Set email header.
   */
  public function setHeader(string $name, string $value): void;

Steps to reproduce

$to = '';
$params['Bcc'] = 'test@example.com,test2@example.com';
.
.
.
$mailManager = \Drupal::service('plugin.manager.mail');
$mail= $mailManager->mail($module, $key, $to, $langcode, $params, $reply, $send);

Proposed resolution

When the to is NULL, add a string as it was on the previous module version.
