Title:
Update tutorial_noisy_circuits.py to port default.mixed free of legacy interfaces

Summary:
In the Tutorial of Noisy Circuits, there's a call dev.state which is a legacy-only interface. In our current standard, the device object will not store the state any more and we should return the latest state via the corresponding measure.

Oh no the current method won't pass the legacy _qubit_device test........ We might need to hold on until the new api merged into PL master.
