Asserts that the most recently sent email message has the string in it.

string $string: String to search for.

int $email_depth: Number of emails to search for string, starting with most recent.

string $message: (optional) A message to display with the assertion. Do not translate messages: use \Drupal\Component\Render\FormattableMarkup to embed variables in the message text, not t(). If left blank, a default message will be displayed.
