PHP Fatal error: Cannot declare class PHPMailer\PHPMailer\PHPMailer

With PHPMailer living in a new directory, including the wp-includes/class-phpmailer.php from code may result in a fatal error, ie.: when running the phpunit.

The change in https://core.trac.wordpress.org/changeset/48033/#file7 requires once the PHPMailer class directly, so the class gets declared. In case there is a plugin requiring the wp-includes/class-phpmailer.php (even when require_once is used), the file requires the file declaring the PHPMailer class again ( see https://core.trac.wordpress.org/browser/trunk/src/wp-includes/class-phpmailer.php?rev=48035#L15 ).

I believe that require_once in wp-includes/class-phpmailer.php should be used in order to prevent mentioned fatal errors.
