Part: Fix several clazy issues:

* Maybe you meant to call Primitive::onChanged() instead [-Wclazy-skipped-base-method]
* Maybe you meant to call Primitive::mustExecute() instead [-Wclazy-skipped-base-method]
* Missing reference in range-for with non trivial type [-Wclazy-range-loop-reference]
* Use multi-arg instead [-Wclazy-qstring-arg]
* Use midRef() instead [-Wclazy-qstring-ref]
