Problem /about/usage/system was not tested

[olethanh]

Solution: Add a test in pytest and a test in droplet

I had to refactor the setup of the web.app test since pytest-aiohttp use a new async loop between each tests.
Also fixed an issue in get_machine_properties where the returned format is not the same between all the machines. note that this code/dep is going to be dropped in #544 so that's not a blocking issue

I think that on Alie's PR (#544) he had installed also the needed packages needed on the installation step.
I don't know if that PR merges also his changes, but if it does, please, can you also add it to this PR? And if not, can you link as dependent this PR to the old one to merge both at the same time?

Alie's PR is not included into this one, in that other PR the deps have changed but here they stay the same so normally the installation step shouldn't change, unless I have missed something?
