Same code committed as upper and lower case

[HenkPoley]

When doing a git checkout under macOS I get the following warning. Which is normally fatal for the integrity of the repository checkout, but I think in this case it is in fact a simple error of committed duplicate code. You might want to clean the duplicate folders.

warning: the following paths have collided (e.g. case-sensitive paths
on a case-insensitive filesystem) and only one from the same
colliding group is in the working tree:
