top_window() not working when minimized application

[blakes22]

Very minor bug (unless it's like that on purpose).
top_window() will not find any window when application is minimized because visible_only argument from find_elements() is False by default - even though process ID and backend are correct.

Current implementation in top_window():

        windows = findwindows.find_elements(process=self.process,
                                            backend=self.backend.name)

Works like a charm after adding visible_only=False.

This is design intended because "win32" apps often has several hidden windows that are useless. We can try something like that: (1) use visible_only=True; (2) if nothing found, try visible_only=False. Does it make sense for you?

One of my thoughts were to remove top_window() method at all because it adds a lot of confusion when real top window is changing. It returns WindowSpecification with the handle at some moment and re-usage of this specification confuses a lot.

I think this issue should be solved after we implement an ability to create child window specifications from wrapper object as a parent in search criteria. So that top_window() could return a wrapper object.

Another possible way is to have top_wrapper() and top_window() equivalent to .window(top_level_only=True, found_index=0). But for UIA backend the meaning of top window is different because top window can be a child of main form. So it can be backend specific and therefore removed from Application object which is backend agnostic.
