fix for folder names without version

[suisseWalter]

potential fix for #99

it works in my space exploration file. but there might be other mods where it might crash.

It looks like this might only work when all loaded mods leave the version off, otherwise it causes the opposite problem and folder names with the version crash:

Apparently this PR crashes for mods that do have a version in the folder name. The problem should probably be addressed at https://github.com/L0laapk3/FactorioMaps/blob/3479b2ac1285658d4dbfbc2e4b4a99b81d113544/auto.py#L741-L747 rather than trying to fix the symptoms. I'll try to have a look at it over the next days or if someone else wants to do it, feel free :p

I believe the --no-tags flag can be used as a workaround until this is addressed.
