Fix rare double-free in QObject machinery
As exposed by tst_QObjectRace::destroyRace we would sometimes end up with a double-free when destroying a QSlotObject in multi-threaded scenarios. One free would be done in ~QObject as the receiver was being destroyed while the other free was done when deleting a QMetaCallEvent object after we realized it was not needed because the receiver was destroyed. Since we can be in a separate thread from the receiver we should lock before referencing the connection object. Amends b7d073e9905bf9812ba96cecdcf6871a95517d30.
