composer install in ./update doesn't use provided credentials

[macieklewkowicz]

When credentials for repo.magento.com are set via set :magento_auth_public_key, '<your_public_key_here>' and set :magento_auth_private_key, '<your_prviate_key_here>', they're being used only when Capistrano runs composer install in Magento root folder but not in ./update.

This is likely due to Composer not loading credentials from ./auth.json when being executed with -d ./update flag.

capistrano-magento2/lib/capistrano/tasks/magento.rake

Line 97 in 2a10a67

execute :composer, "install #{composer_flags} -d ./update 2>&1"

@macieklewkowicz Interesting…Think I'm going to look at addressing this in context of #82.
