Legends processor module can't locate exported files

Since DFHack 0.47.04-r2 exportlegends "added ability to save all files to a subfolder, named after the region folder and date _by default_" the legends processor module can't locate the new legends files exported with the default "exportlegends info/all", unless they were exported to the top DF folder with "exportlegends info/all ."
