Laravel 5.1 to 5.2 upgrade error

When I try to update our existing project from Laravel 5.1 to Laravel 5.2 using the official guide, I get an error after composer update when the post update

php artisan clear-compiled

is run. Here is the error.

Class Illuminate\Foundation\Composer does not exist

Has anyone had a similar problem? When I run composer update with the no scripts flag it updates regularly so it's a problem on the clear-compiled.

Below are my Service Providers and my composer.json file.
