Title: Updated task description to install Composer after deploy:starting

This fixes the first install when directories does not exist.

To be consistent with install path (shared folder), `composer:install_executable` task cannot be called before `deploy:check:directories` (so `deploy:starting`) which creates directories if necessary.
