side-nav - onMinimize and onClickCollapseButton events not triggered properly

Unless I'm doing something wrong, it seems like the `onMinimize` and `onClickCollapseButton` event handlers (both from `SideNav` and `SideNav.Module`) are being triggered when the component is mounted instead of when the event is actually triggered.

You can see this behavior on the following sandbox, the console shows all the `console.log`s on mount and the alert as well. I thought the alert should be when the collapse button is clicked.

Thanks in advance!

Reproduce the behavior in the linked CodeSandbox, then locate the SideNav and SideNav.Module implementations and inspect how onMinimize and onClickCollapseButton are passed or invoked. Done means the handlers remain silent on mount and fire only when the corresponding collapse interaction occurs, for both components.
