Update dataset to default values from array not working

### Expected behavior

When deleting a dataset property (or setting it to null) it should have its default values after `chart.update()`, independent if it was a single value or an array.

### Current behavior

When deleting a dataset property (or setting it to null) when it was an array does not reset its default value.

### Reproducible sample

https://codepen.io/Ipax77-the-flexboxer/pen/jOJoWqJ

### Optional extra steps/info to reproduce

Click "Update Test Arrays" then "Reset"
("Update Test Single" then "Reset" is working as expected)

### Possible solution

It is working when you do a chart.update() after setting each property to null (codepen line 43), but then you have multiple animations (or none with chart.update('none')).

### Context

I want to be able to update datasets with animations for my [Blazor wrapper library](https://github.com/ipax77/pax.BlazorChartJs).
