Apparently since I am using WPGlobus plugin for multiple languages this would not work for me. Just wanted to write it here for somebody to save a few hours trying to disable auto formating while using WPGlobus plugin.
The solution with WPGlobus plugin:
Apparently it passes everything trough the wpautop function in the plugin. It is in the file wp-content\plugins\wpglobus\includes\class-wpglobus.php
I changed
$post_content_autop = wpautop( $post_content );
to
$post_content_autop = $post_content;
in the file and it disabled all autoformatting for me while using WPGlobus plugin.
Hope this helps somebody not to go through what I just did.
