When setting config and unsettling config again, an empty config section still remains in composer.json #7691
Description
My composer.json, I created with composer init:
{
"name": "7ochem/composer-test",
"description": "Showing config unset leaves empty config",
"type": "project",
"license": "proprietary",
"minimum-stability": "stable",
"require": {}
}Output of composer diagnose:

And I expected that if the config (and underlying platform) section is empty, it will be removed again and restoring the composer.json to its original state and thus git diff not showing any changes.
Upon running composer init Composer doesn't generate a config section. So I also expect composer to restore it to that state when I use Composer to remove all configuration through it's built in commands and thus leaving no changes in the state of my VCS.
