service_account_scopes nilclass

[bgeesaman]

Description

If a google_compute_instance has no service account scopes assigned, the following logic:

    describe "[#{gcp_project_id}] Instance #{instance[:zone]}/#{instance[:name]}" do
      subject { google_compute_instance(project: gcp_project_id, zone: instance[:zone], name: instance[:name]) }
      its('service_account_scopes') { should_not include 'https://www.googleapis.com/auth/cloud-platform' }
    end

causes:

     ×  [my-project] Instance us-central1-f/my-instance service_account_scopes 
     undefined method `[]' for nil:NilClass

This adds a quick check to see if that dynamic method is available before seeing what's in the array.
