Refactor settings

Just some minor housekeeping for readability

On my local machine the install test needs os.remove(os.path.join(execution_path, "pyiron.log")) in TearDownClass or I get a pyiron.log leftover in the test directory. But on the CI this gives

FileNotFoundError: [Errno 2] No such file or directory: '/home/runner/work/pyiron_base/pyiron_base/tests/settings/pyiron.log'

For now I just wrapped the removal in a try/except FileNotFoundError because I want to keep my system clean, but I'd feel better understanding where pyiron.log winds up on the CI system if not at execution_path...

Why is this part removed? I though we need it to run the tests in the continuous integration environment.

That's a very good warning!!! It's not necessary on my local machine so I thought I was removing dead code. I'll just burn some CPU minutes and do a brute-force tests by throwing a failing test in one of these suites to see if the CI catches it.

[liamhuber]

Indeed, it's safe to remove the __main__ boilerplate. I added this to one of the modules that had had the boilerplate stripped and the CI caught it no problem:

    def test_should_fail(self):
        self.assertTrue(False)

I'm going to revert the change and resolve the other two instances, but it was a very good call to double check this behaviour!!!
