fix(api): loading viz_type from request params

[hdahme]

SUMMARY

Previously, when passing viz_type via the API, it would default to table. This change allows us to send viz_type and have the charts respect it in the UI

TESTING INSTRUCTIONS

Make an API request via python and send the following params

params = {
        "viz_type": "big_number",
        "groupby": columns,
        "metrics": metrics,
        "adhoc_filters": [
            {
                "expressionType": "SQL",
                "sqlExpression": where_clause,
                "clause": "WHERE",
            }
        ]
    }

The resulting chart would always be a table. No longer
