[v4.0.0-rc.1] does not support correctly the BOX dump-autoload setting

[llaville]

Summary

Following my comment on BOX dump-autoload setting BOX Manifest 4.0.0RC1 did not include the Composer autoloader (vendor/autoload.php) when dump-autoload was not previously defined.

Expected behaviour

Be able to compile a PHAR with BOX 4.6 that include both manifests and Composer autoloader

Actual behaviour

Composer autoloader is not found and if following message is defined, it will be displayed

You need to set up the project dependencies using Composer:

    composer install

You can learn all about Composer on https://getcomposer.org/.
