[PyQt] [BUG] QQmlComponent.create() marks item owner as C++ and they never garbage collected

[Vladimir Rutsky]

Hello,

QQuickItem's objects created with QQmlComponent.create() are owned by
C++, so when Python variable is being garbage collected item is not
destroyed.

As workaroud I can manually call "sip.transferback(item)" for item -
after this item is properly garbage collected.

I prepared complete example to reproduce this bug:
