generate_box.sh always requires AWS configuration

[carmenbianca]

I am working on a machine that has no AWS configuration. I want to use VirtualBox as provider. When I go through all the steps and reach cd generate-box; ./generate_box.sh, I get the following error:

$ ./generate_box.sh                                                                                            
No previously created folder found, moving on.
-[] Destroy old box (if created previously and script exited with failure)
There are errors in the configuration of this machine. Please fix
the following errors and try again:

AWS Provider:
* One or more of the needed AWS credentials are missing. No environment variables
are set nor profile 'default' exists at '/home/carmenbianca/.aws/'
* An access key ID must be specified via "access_key_id"
* A secret access key is required via "secret_access_key"
* An AMI must be configured via "ami" (region: #{region})

This happens on the master branch without any modifications.

I doubt that this is intentional?
