missing reference count in policy list breaks idempotency

[craigers521]

Using the vmanage_policy_list module, if you don't define variable "referenceCount" in policy list definition it registers as a change. I dont feel like referenceCount should be tracked in the diff as this is subject to change as list is used additonal places and isnt necessary to define the list.

Example:

"results": [
            {
                "ansible_loop_var": "item",
                "changed": true,
                "failed": false,
                "invocation": {
                    "module_args": {
                        "aggregate": [
                            {
                                "description": "Desc Not Required",
                                "entries": [
                                    {
                                        "siteId": "1101001-1150999"
                                    }
                                ],
                                "infoTag": "",
