Named maps dataviews with invalid options

Most of the dataviews created in named maps contain non-required options and sometimes invalid options. Example from https://github.com/CartoDB/cartodb/issues/7520:

"ebc0653f-3581-469c-8b31-c969e440a865": {
            "options": {
                "aggregationColumn": null,
                "column": "exp_job_loss_fraction",
                "operation": "avg",
                "prefix": "",
                "schema": {},
                "suffix": "",
                "sync_on_bbox_change": true,
                "sync_on_data_change": true
            },
            "source": {
                "id": "a0"
            },
            "type": "formula"
        }

aggregationColumn exists as an option but doesn’t apply to a formula type, just for aggregation type. And prefix, schema, suffix, sync_on_bbox_change, and sync_on_data_change have nothing to do with Maps API, probaby they are frontend related so we should not send them in the named maps.
