XRay returns unsorted data and duplicates in x-values

[pawelfus]

Note: This is pre-release (v1.1.0) issue, might get resolved in the meantime, needs to be revisited after the release.

Example:

    const xRayConnectorMultiStrategy =
        new HighchartsConnectors.Morningstar.XRayConnector({
            api: {
                access: {
                    token: token.access_token
                }
            },
            currencyId: 'EUR',
            benchmarkId: 'EUCA000812', // Multistrategy EUR
            frequency: 'annual',
            dataPoints: {
                type: 'portfolio',
                dataPoints: [
                    ['HistoricalPerformanceSeries', 'TotalReturn', 'M1'],
                    ['PerformanceReturn', 'M1', 'M3', 'M6', 'M12', 'M36', 'M60']
                ]
            },
            holdings: [
                {
                    id: 'EUCA000812', // Multistrategy EUR
                    idType: 'MSID',
                    type: 'FO',
                    weight: 100
                }
            ],
            startDate: '2020-01-01'
    });


    // Load data
    await xRayConnectorFund.load();
    const fundData = xRayConnectorFund.table.getRows(0);

    console.log(fundData);
