x-axis setup wrong in expensive setting

[brockho]

Describe the bug
In the expensive setting, the x-axis is wrongly scaled in the latest cocopp version:

Before, we had way shorter runtimes (up to 10^3 times dimension only) displayed such that most of the plot wasn't just white. Many thanks to @rleriche for actually reporting this issue in a call earlier today.

Your System (please complete the following information when it seems relevant):

• Operating system: shouldn't matter
• COCO version: latest 2.6.2

I can reproduce the bug. Before the bugfix, you might want to go back to an old version:

1. Download version 2.4 here: https://github.com/numbbo/coco/releases [download links are at the bottom of each release.]

2. Because in previous versions like 2.4, we had hard-coded links to the previous webpage at coco.gforge.inria.fr which is now down and replaced by numbbo.github.io/data-archive/, an additional step has to be done: Once you downloaded and unzipped the file, you will have to find the file archiving.py in code-postprocessing/cocopp/ and replace the line

   coco_url = "https://coco.gforge.inria.fr/"

with

coco_url = "https://numbbo.github.io/data-archive"

3. Then install the cocopp package from your local folder by typing within the folder where the file do.py is located:

   python do.py install-postprocessing

This worked for me and resulted in the correct x-axis again.

If the above does not work immediately, uninstall the cocopp module by typing pip uninstall cocopp --yes until the output says there is nothing to uninstall. Now, the python do.py install-postprocessing should work.

We identified commit f5289e3 as a potential reason (though we don't understand how) and decided, due to lack of other ideas, to test whether the error remains before/after this commit specifically.

Now I actually understand the problem, will provide a fix.

Should be fixed with the latest update of the development branch (though I didn't cross-check the output).

Thank you Niko!
