Update output repository before loading results

[schmoelder]

This PR adds a call to output_repo.update() so that we always consider the latest results when loading from cache.

We could also make this optional via an argument, what do you think @hannahlanzrath?

Note, this builds upon #112

Great thanks!

In my head, I could not think of a good scenario where I would not want to have my up to date output repo when I load from cash, so I think I would leave it with your commit for now.

In my case, I'm loading many cases at once, so it always checks and it does always take some seconds. But it's not a dealbreaker.

Alright, then let's merge it and if it gets annoyingly slow let us think of solutions then!
