ParallelTestRunner.jl

[lkdvos]

This is a minor change to alter the tests to use the ParallelTestRunner.jl interface.

To make this work, I also had to update the printing machinery slightly, since string(x) does not now about the context, so it would print types as if they are shown in the Main module, which doesn't necessarily have AlgorithmsInterface loaded.
This became visible here since ParallelTestRunner starts new processes to really isolate the tests, therefore you can't really control what is visible in Main (and @eval Main using AlgorithmsInterface feels very wrong 😉 )

Let me know if the explanation is clear enough, I'm happy to include a small readme file in the tests as well if you think that could be helpful

Re the changelog, given that we haven't released anything yet I don't think it is that helpful to update this, so if you are okay with it I would just keep this for now.

Sure, the Changelog can be ignored here. It is really just to later have in mind that at least one itemise point per PR would be nice.
