This is still not ideal: consider the case where the metadata is empty and the status is "RUNNING".
Then first self._status(True) is called, filling the metadata and returning the "RUNNING" status.
Since it's not a terminal state, self._status(False) will be called again. This uses two GetQuantumTask calls.

However, there will be at most one extra call to GetQuantumTask, and since the status isn't terminal, I don't think it hurts to make the extra call; it's going to have to poll again regardless. Easy enough to get rid of it though.

In the scenario I described it's two successive calls to GetQuantumTask, so the second call will likely return the same result and be wasted. In any case, thanks for the fix.
