Fix re:replace/4 to handle binary unicode output when nothing replaced
A bug with re:replace/4 causes an exception when: (a) it's given a unicode charlist as input; (b) it's set to {return,binary}; and (c) it finds nothing to replace. The problem is: when re:replace/4 does not find anything to replace in its Subject input, it calls iolist_to_binary on this data. This fails if the original input is a charlist with non-ascii codepoints.
