[web] don't rename resources in gen-static-datadir We should use the result from WebConfiguration.locate_resource to know which file to copy, not what name to copy it to. The destination file should be the name of the resource, as the client will request it. This matters in the case of cubicweb.css which locate_resource might rewrite to cubicweb.old.css. Closes #3206129
