google::address description field isn't actually being changed

[jortiz98]

Describe the bug
When creating a google::address resource, you can optionally add the description field to the resource. However, after creating the resource and looking it up via gcloud cli, it's description is an empty string. This is in conflict with the state files that do set the description field to the expected behavior

To Reproduce
Create a google:address resource with a description

ex. env = qa, layer = qa

    google::address "elastic-ip"
        name: "test-ip"
        address-type: "EXTERNAL"
        description: 'External Static ip for $(layer) instance in the $(environment) environment'
        network-tier: "PREMIUM"
        region: $(base-region)
    end

Now run the below command to see the info for the resource:
$ gcloud compute addresses describe test-ip

Expected behavior
description: 'External Static ip for qa instance in the qa environment'

Actual bahavior
description: ''
