Warning when auto-upgrading core

Warning: version_compare() expects parameter 2 to be string, object given in /srv/www/wordpress-default/wp-admin/includes/class-wp-upgrader.php on line 2138

Just to confirm, version_compare() returns NULL in this case, so $newer_version_available would be false.

Basically, this variable is for using different language in the email when we've auto-updated them to 3.7.4 but 3.8.2 is available. If someone is on 3.7 and is somehow not auto-updated to 3.7.1, but they later enable automatic updates and get to the point where 3.7.4 and 3.8.2 are released at the same time, that's really the only time they'd be affected by this change.

I wish there was a way for us to "hotfix" this. As it stands this file clocks in at 2400 lines but isn't otherwise modified in 3.7.1, so it'll increase the size of the partial zip quite a bit. Not a big deal, though.

In 25977:

Use correct variable in WP_Automatic_Updater::send_email().
