[FIX] Charts: Ensure Chart js extension are loaded on chart creation

[rrahir]

When calling the method chartToImage, the chartJs extensions might not be loaded as we load them conditionally when mounting a chart. Hence, calling ChartToImage when there are no visible charts in the viewport or if we just instantiate a model without loading a component Spreadsheet, the extensions will be missing.

Right now, the plugins/extensions are not fundamental to convert a chart to an image but this becomes problematic with the arrival of future charts (for instance Funnel).
