Just copies the sorting from generateFromPath()

Thanks!

@Jellyfrog this PR breaks existing behaviour, please see #108
Feel free to resolve. In the meantime we will revert this PR.

I honestly don't understand the problem of #108

(new SplFileInfo($fileinfo))->getFilename() resolves now the symlink and returns lang instead of core and user when calling $fileinfo->getFilename() directly.
