"pie": Runtime errors when setting legend position to "left" or "right"

### Expected behavior

It is unacceptable that changing the legend position from "top" to "left" or "right" in Chart.js using Angular v4.x.x results in runtime errors when chart options are null. This issue needs to be addressed and resolved immediately.

### Current behavior

When changing the legend position from "top" to "left" or "right" in Chart.js starting from `v4.x.x` using Angular. it causes runtime errors whereas chart options are `null` for no reason. Which should be working as usual. ,
