Item/PathView: reset the currentItem before releasing itHEADdev

releaseItem ends up in code paths that emit signals and might activate
bindings or handlers, potentially leading to recursion. Since the
released item is deleted in releaseItem, this results in a dangling
pointer and potential crashes.

To prevent that, reset the currentItem pointer before we release it.
Add a helper function that encapsulates that before calling the (virtual
in case of QQuickItemView) releaseItem method.
