Comment (by dlh):

 After [51815], a database error occurs when installing WordPress from `wp-
 admin/install.php` because there's an attempt to write the `cron` option.

 A `! wp_installing()` check inside
 `\WP_Upgrader::schedule_temp_backup_cleanup()` might be all that's needed,
 but I'm not familiar enough with the changes in this ticket to be sure
 whether it's the right approach.
