QmlDesigner: Remove parent from abstract view

We apply not very often the parent to views. So it can lead to dangling pointer if the parent is used by other objects and does not handle the null pointer case. It can lead to double deletion if the parent is deleted before the object when it is on the stack or handled by smart pointer. If you really want to use it there is still setParent.
