Subject: [PATCH] Refresh chart when a series is removed

Removing a series from the chart only dropped it from the Series list
without rebuilding the category/value scales. When a RadzenChart
instance was reused across a render that replaced its series, new
series' Data callbacks would refresh the scale while the outgoing
series were still present, and after they were finally disposed the
scale kept the stale categories. Triggering a refresh on removal
rebuilds the scales from the live series set.
