Fix for ember-bootstrap v5.1

Was throwing with `Assertion Failed: <PowerSelect> requires an `@onChange` function` as the components still referred to properties on `this` that don't exist anymore since ember-bootstrap/ember-bootstrap#1772. See failing [CI](https://github.com/kaliber5/ember-bootstrap-power-select/runs/6518834502?check_suite_focus=true#step:5:312)
