function flat_comments_calculate_thread in Flatcomments 8

By the time we reset the `pid` of the comment, the thread has been already calculated, so in order to make sure that the comments are completely flattened we need to recalculate the thread.

This code was mainly taken from Drupal\comment\Entity\Comment::preSave();

function flat_comments_calculate_thread($comment) {
  $comment_storage = \Drupal::entityTypeManager()
    ->getStorage('comment');

  // This is a comment with no parent comment (depth 0): we start
  // by retrieving the maximum thread level.
  $max = $comment_storage
    ->getMaxThread($comment);

  // Strip the "/" from the end of the thread.
  $max = rtrim($max, '/');

  // We need to get the value at the correct depth.
  $parts = explode('.', $max);
  $n = Number::alphadecimalToInt($parts[0]);
  return Number::intToAlphadecimal(++$n) . '/';
