build(autoloader): Remove noisy changes when regenerating

[provokateurin]

Summary

When executing the script all the app/*/composer/composer/installed.php files change as they reference the current HEAD commit hash. To avoid having to manually discard the changes, just drop them automatically.

Checklist

• Code is properly formatted
• Sign-off message is added to all commits
• Tests (unit, integration, api and/or acceptance) are included
• Screenshots before/after for front-end changes
• Documentation (manuals or wiki) has been updated or is not required
• Backports requested where applicable (ex: critical bugfixes)

Is there no option to prevent those updates in the first place?
Approved, as fine with this solution thought.

Skip the composer install ... part and only run composer dump-autoload ....

I wonder if not doing it could cause any problems. I don't see why we need to do it first before dumping the autoloaders, so we might just get rid of it in the first place?

I checked and it is necessary, so this is the way to go for now.
