Add test to check bsp ignores OnEnd and ForceFlush post Shutdown` (#1772)

Browse Source 
* Add test to check bsp ignores OnEnd and ForceFlush post shutdown

* Add to CHANGELOG

* Check for err return value

* Stop test execution if there's error with shutting down bsp

Co-authored-by: Tyler Yahn <MrAlias@users.noreply.github.com>

* Use assert to check there's no error calling bsp.ForceFlush()

Co-authored-by: Tyler Yahn <MrAlias@users.noreply.github.com>

* Import require

* Add error message for assertion on be.len()
