Do `bin/magento module:enable --all` before doing setup:di:compile

[7ochem]

We experienced DI errors on our Magento2 setup in Platform.sh. As stated and confirmed by @damz :

this is what the latest code in magento/magento-cloud-configuration is doing:

    protected function compileDI()
    {
        $this->log("Run DI compilation");
        $this->execute('rm -rf var/generation/*');
        $this->execute('rm -rf var/di/*');
        $this->execute("cd bin/; /usr/bin/php ./magento module:enable --all");
        $this->execute("cd bin/; /usr/bin/php ./magento setup:di:compile");
    }

The code in platformsh/magento2-configuration, which is an earlier iteration of the same, does this instead:

    public function compile()
    {
        $this->log("Compiling generated files.");
        $this->execute("php bin/magento setup:di:compile-multi-tenant");
    }

Indeed, if on the environment I launch php bin/magento setup:di:compile-multi-tenant manually it does get the right modules
