Migration Generator: Foreign keys are created even though they already exist

[cebe]

When a table has been created with foreign keys, the next generator run will include a migration again that adds the same foreign keys.

Example:

<?php

/**
 * Table for Task
 */
class m200803_210003_change_table_tasks extends \yii\db\Migration
{
    public function safeUp()
    {
        $this->addForeignKey('fk_tasks_project_id_projects_id', '{{%tasks}}', 'project_id', '{{%projects}}', 'id');
        $this->addForeignKey('fk_tasks_creator_id_users_id', '{{%tasks}}', 'creator_id', '{{%users}}', 'id');
    }

    public function safeDown()
    {
        $this->dropForeignKey('fk_tasks_creator_id_users_id', '{{%tasks}}');
        $this->dropForeignKey('fk_tasks_project_id_projects_id', '{{%tasks}}');
    }
}

@Insolita You should be able to reproduce this in the layer5 project when running ./yii gii/api.
