Duplicated series in chart after filter is removed

[zbodi74]

Describe the bug

Removing a post-aggregation filter causes duplication of data on a single series chart.

To Reproduce

1. Create a GUI question: Orders, Summarize: Count of rows, Group by: Product --> Category
2. Add filter post aggregation: Product --> Category is not empty
3. Visualize: select Bar (or Row)
4. Save it
5. Edit the question and remove the filter
6. The series is now duplicated, and the error persists if the question is saved.

Expected behavior

The duplication should not happen.

This is an FE issue.

Following the steps above, at step 4 these are the visualization_settings of the card:

    "visualization_settings": {
        "graph.dimensions": [
            "CATEGORY"
        ],
        "graph.metrics": [
            "count"
        ]
    },

After saving at step 6, the visualization_settings have a duplicated count metric:

    "visualization_settings": {
        "graph.dimensions": [
            "CATEGORY"
        ],
        "graph.metrics": [
            "count",
            "count"
        ]
    },
