Fix dashboard evolutions

[joanagmaia]

Changes proposed ✍️

• Fix previousDateRange in dashboard-count.vue component. The request was being done with a wrong dateRange, where the most recent date was before the oldest one. To fix this, the order of the dates within the previousDateRange were switched. Since this component is global, this will fix the dashboard evolutions for all dashboard widgets
