__home__ slug gets rewritten to home on save

[nilsenpaul]

Description

If we want to define an entry as the site's homepage, we always set the slug to __home__. As of the last update, this gets automatically rewritten to home, which stops the homepage from being found.

Steps to reproduce

1. Create an entry with slug __home__
2. Save it, re-open it and see the slug changed to home

Additional info

The problem is solved in a very quick and dirty way, if I change line 42 in craftcms/cms/src/helpers/ElementHelper.php to:

if ($str !== '__home__') {
    $str = StringHelper::toKebabCase($str, $glue, $lower, false);
} 

• Craft version: 3.1.21

Sorry about that. Just released 3.1.21.1 which fixes this.
