WidgetsAskUserActionHandler: Use QPointer to check the validity of parent
widgets

If Dolphin is closed during the copying process,
and the overwrite/skip dialog appears,
this crashes the copying process since the
parent shows to faulty location.

Use QPointer to check that the parent widgets are still
valid. If not, we just use nullptr, and the dialogs
will still open.

This also cleans some repetition in code.
