show different field than name for belongsTo

@alev You can find it in documentation

From docs: https://nova.laravel.com/docs/3.0/resources/relationships.html#belongsto

To customize the "title" attribute of a resource, you may define a title property on the resource class:

public static $title = 'email';

Alternatively, you may override the resource's title method:

/**
 * Get the value that should be displayed to represent the resource.
 *
 * @return string
 */
public function title()
{
    return $this->email;
}

Ah. Now I get it. I had to set the title on the resource Users and not on the resourceReminders, event hough I want to show it on Reminders.
