Not working with the Qiskit==0.13.0 version

Dear @adelshb 

While I was inspecting the code I found the following:

`quantum_instance = QuantumInstance(backend, shots=shots, seed=random_seed seed_transpiler=random_seed)`

Why both seed and seed_transpiler variables are set to the random_seed?

Also in Qiskit==0.13.0 version, the code is not executing. It is not giving error but I guess it enters in an infinite loop. 

Regards
