Thanks for the review @Cryoris. I modified few existing tests, all gradient modules are tested also with I did minor change in handling the |

As reported on multiple occasions in Qiskit Aqua ([1], [2]), the eigenvalues of the auxiliary operators are not correctly normalized when the QASM backend is used. This commit fixes this short-coming by applying the same normalization to the VQE's eigenstate when obtained from a QASM backend (in which case this is a dictionary) as done by the `CircuitSampler` in its `sample_circuits` function. The case of the statevector backend is unaffected by this change, as it will return the eigenstate as a list. A unittest is added which asserts this behavior.
