QtQuick: fix use-after-free of shader property connections

A use-after-free would occur if the sender of a connection would
disconnect (and destroy the slot object), and then the receiver would
try to clean-up and access the slot object again. The fix is to have
the receiver take out a reference to the slot object, because it will
manage the life-time, and thus delete the slot object when it doesn't
need it anymore.
