Fix FilterListItem doesn't accept object values

[mjattiot]

If the filter value is a nested object, the component is unable to find out if it is selected.

Could you give an example of the usage you're doing of nested object values?

Sure. Our filters are mongo queries that are serialized to a REST API. It looks like this :

<FilterList
        label="resources.goldens/disclosures.fields.marketData.DsclsrRspnDdln"
        icon={<AccessTimeIcon />}
    >
        <FilterListItem
            label="dates.filters.today"
            value={{
                $and: [
                    {
                        'marketData.IssrDsclsrDdln.Dt.Dt': {
                            $gte: { $date: startOfToday().toISOString() },
                        },
                    },
                    {
                        'marketData.IssrDsclsrDdln.Dt.Dt': {
                            $lte: { $date: endOfToday().toISOString() },
                        },
                    },
                ],
            }}
        />

Now I understand. Thanks!
