QFuture: fix continuation cleanup
Not clearing the continuationData could lead to use-after-free when
there is an attempt to cancel an already finished future, which belongs
to an already-destroyed promise.
This patch fixes it be explicitly resetting continuationData to nullptr
in the clearContinuation() method, which is called from the QPromise
destructor.
