Bug report

The changes related to #2970 causes a "props.groupComponent is undefined" error in our VictoryBar wrapper.

In order for a wrapper to work properly, some static props need to be hoisted (e.g., `role`). Our workaround is to not hoist `getBaseProps`, but would still like to fix `victory-bar/src/victory-bar.tsx` and `victory-bar/src/helper-methods.ts`.

Expected behavior

Use a "?" character when testing `props.groupComponent?.type`, so an error isn't thrown in `victory-bar/src/victory-bar.tsx` and `victory-bar/src/helper-methods.ts`.

Actual behavior
