lib/strings: forbid lists in isStorePath
When a list is passed to isStorePath this is most likely a mistake and it is therefore better to just return false. There is one case where this theoretically makes sense (if a list contains a single element for which isStorePath elem), but since that case is also probably seldomly intentional, it may save someone from debbuging unclear evaluation errors.
