Time travel queries for objects with a status field not showing in before/after JSON

[jathanism]

Steps to reproduce

• Create an object that has a status field (like a Device) setting the status to Active
• Create a new branch
• Change the status field value to another value (e.g. Planned)

Expected behavior

• The column should render with before/after values

Observed behavior

• No before/after in the column
• The commit reflects the change from "Active" to "Planned"

• But the diff table view does not reflect this:

Debug

I was attempting to fix this by debugging the inner render_before_after_diff() function inside of dolt.dynamic.diff_factory.DiffListViewBase.wrap_render_func().

On line 249 in the code, I am seeing that the value variable is "Planned" when it should be "Active" since this should be the before state:

(Pdb) value
<Status: Planned>

I confirmed that the JSON blob being generated in the from/to query annotations is missing the from_status and to_status fields. In this debug example the object was not a Device, but the issue appears to the the same:

(Pdb) print(json.dumps(record.diff, indent=4))
{
    "diff_type": "modified",
    "from_asn": 1668,
    "from_commit": "2q52d50tovr5fh4pk3bgn47gbaar7bt5",
    "from_commit_date": "2021-09-10T19:33:03.851Z",
    "from_created": "2021-09-10T00:00:00Z",
    "from_description": "ATDN",
    "from_id": "de25a1c7a76a48ed94811d9a96018489",
    "from_last_updated": "2021-09-10T19:33:03.632807Z",
    "root": "to",
    "to_asn": 1668,
    "to_commit": "veumh6tms0pmv4il05jlnpsucjdqs1ae",
    "to_commit_date": "2021-09-10T19:59:01.928Z",
    "to_created": "2021-09-10T00:00:00Z",
    "to_description": "AOL Transit Data Network",
    "to_id": "de25a1c7a76a48ed94811d9a96018489",
    "to_last_updated": "2021-09-10T19:57:37.601194Z"
}

It appears to me that the to_queryset and from_queryset inside of dolt.diffs.two_dot_diffs() need to be tweaked a little.
