Detailed Description

The change should transform calls like:

    {
        "name": "Some name",
        "project": {
            "created_at": datetime.datetime(2015, 12, 16, 11, 2, 10, tzinfo),
            "id": 72,
            "name": "Demo: Game",
            "type": "Project",
        },
    },
)

as if the following had been called:

sg.update('Asset', 123, {'name': 'Some name', 'project' : {'id': 72, 'type': 'Project'}})

The base branch was changed.
