ovirt: Resolve also list of hrefs

[machacekondra]

SUMMARY

This PR add fixes to resolve also list of href in case of using fetch_nested=true

Direct elements works, e.g. disks:
<quota href="/ovirt-engine/api/datacenters/87bc2e30-f3b1-11e8-aa7d-001a4a013f36/quotas/96f2a2e4-f3b1-11e8-82b6-001a4a013f36" id="96f2a2e4-f3b1-11e8-82b6-001a4a013f36"/>
-->
"quota": {
                "href": "/ovirt-engine/api/datacenters/87bc2e30-f3b1-11e8-aa7d-001a4a013f36/quotas/96f2a2e4-f3b1-11e8-82b6-001a4a013f36",
                "id": "96f2a2e4-f3b1-11e8-82b6-001a4a013f36",
                "name": "Default"
            },

But when the element is in a list or other element, it doesn't work, e.g. in disks:

        <storage_domains>
            <storage_domain href="/ovirt-engine/api/storagedomains/82ceb4c9-e844-4fc7-b0ff-559052e6301f" id="82ceb4c9-e844-4fc7-b0ff-559052e6301f"/>
        </storage_domains>
-->
            "storage_domains": [
                {
                    "href": "/ovirt-engine/api/storagedomains/82ceb4c9-e844-4fc7-b0ff-559052e6301f",
                    "id": "82ceb4c9-e844-4fc7-b0ff-559052e6301f"
                }
            ],

or template:

        <version>
            <version_name>base version</version_name>
            <version_number>1</version_number>
            <base_template href="/ovirt-engine/api/templates/264640fc-1b51-4263-995b-47e3e9dd3c8f" id="264640fc-1b51-4263-995b-47e3e9dd3c8f"/>
        </version>
-->
            "version": {
                "base_template": {
                    "href": "/ovirt-engine/api/templates/264640fc-1b51-4263-995b-47e3e9dd3c8f",
                    "id": "264640fc-1b51-4263-995b-47e3e9dd3c8f"
                },
                "version_name": "base version",
                "version_number": 1
            },
