Fatal error on new node creation for translatable node

Problem/Motivation

When the node is translatable, if the node does not yet exist, a fatal error occurs:
The website encountered an unexpected error. Please try again later.Drupal\Core\Entity\EntityStorageException: SQLSTATE[22001]: String data, right truncated: 1406 Data too long for column 'status' at row 1: INSERT INTO {gathercontent_operation_item} (uuid, operation_uuid, item_status, item_status_color, item_name, template_name, status, gc_id, nid, created, changed) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3, :db_insert_placeholder_4, :db_insert_placeholder_5, :db_insert_placeholder_6, :db_insert_placeholder_7, :db_insert_placeholder_8, :db_insert_placeholder_9, :db_insert_placeholder_10);...

This happens because the 'title' is left blank if the node is translatable:

    if (!$is_translatable && empty($entity->getTitle())) {
      $entity->setTitle($gc_item->name);
    }

in gathercontent/src/Import/ContentProcess/ContentProcessor.php

Proposed resolution

Set title if empty on translatable node types as well.
