Update the name of the FakeVigo backend in simulators/2_device_noise_simulation.ipynb

1

In **simulators/2_device_noise_simulation.ipynb** tutorial, the `FakeVigo` backend is referred to as `ibmq_vigo` ([here](https://github.com/Qiskit/qiskit-tutorials/blob/master/tutorials/simulators/2_device_noise_simulation.ipynb?short_path=03a7303#L53) and [here](https://github.com/Qiskit/qiskit-tutorials/blob/master/tutorials/simulators/2_device_noise_simulation.ipynb?short_path=03a7303#L124)) however when running `device_backend.backend_name` what is returned is `fake_vigo`. In the code this name is explicitly...
