Set parent of internal socket objects

After moving the websocket into another thread
current code doesn't work because then the QTcpSocket/QSslSocket
objects reside in a different thread, for instance:
"QSocketNotifier: Socket notifiers cannot be enabled or disabled from another thread"

QObject::moveToThread(QThread*) also moves QObjects's children,
therefore their internal socket objects need to be children of QWebSocket.

QWebSocket has ownership of the internal socket, and the
smart pointer is not needed any more.

Change of cleanup code to prevent crashes with clang/msvc builds:
QWebSocketPrivate is a scoped member of QObject (not QWebSocket)
and is destroyed after QObject destructor body was executed,
and so  m_pSocket&co had already been destroyed (being children)
when the destructor of QWebSocketPrivate is called via the
scoped pointer.

Analogous to 64927e04f202d33b9a9a1f94141ef692c0b513ac
