CI: Avoid two steps to access azure-pipelines logs
When we are in a PR, we got the list of all CI checks:

If we click in travis, it takes us to the travis log build, which seems reasonable. But when we click in one of the azure-pipelines builds, it takes us to this "Checks" tab, that how we have configured azire-pipelines, it provides literally no value, at least to me (never seen any useful information there):

![azure2](https://user-images.githubusercontent.com/10058240/59569872-aaad9c80-9087-11e9-840e-f708b9409069.png)

Then what afaik we all do, is immediately click on the `View more details on Azure Pipelines `, so we go to azure-pipelines, and we can see the errors (if we have them highlighted, like for the linting), or we can click in the step and see the log:

![azure3](https://user-images.githubusercontent.com/10058240/59569873-ab463300-9087-11e9-9f81-09b6ab874ca1.png)

I guess we have something configured incorrectly, because the second step (the "Checks" tab) doesn't add any value, it's just making things more complex for no reason.

@davidstaheli @vtbassmatt do you mind helping us here? What are we missing? It's not only us, checked numba and scikit-learn, and they've got the same as us. Thanks!
