Bugfix: Collection of small fixes to make examples work again

[spenke91]

We realized the examples were not properly working. This PR adds some minor fixes to ensure they are working as expected, i.e., as the original t8code tutorials.

Thanks! Could you please run the formatter?

julia -e 'using Pkg; Pkg.add(PackageSpec(name = "JuliaFormatter", version="1.0.60"))'
julia -e 'using JuliaFormatter; format(".")'

We should run the examples in CI to ensure they are working, cf. #29. Would you be willing to add such a GitHub action?

Hi @JoshuaLampert , thanks for your comment (which I somehow didn't notice until now). Sure, I will add it to the CI.

Speaking of the CI: Do you have any idea why the CI is not working anymore? There seems to be some kind of SegFault. I started playing around in #86 a little, but can not yet really identify it...

Yes, I noticed that, too. However, I don't know where it comes from. Interestingly, in this PR, CI is passing.

Ok, after rerunning, it is also failing here. Looks like it's non-deterministic 😕

If I saw this correctly in the dummy PR, it sometimes worked and sometimes failed, which hints towards some memory bug 🤔

[JoshuaLampert]

Yes, probably. Have you been able to find out, which specific test causes the problem?

Well, I thought I had narrowed it down to the test cmesh/test_readmshfile.jl and this part:

However, this was before I realized the bug was non-deterministic, so one would have to double-check 🙄
