Fix bug with multiple iconv conversions in one dir The internal buffer in the `git_path_iconv_t` structure was not being reset before the calls to `iconv` were made to convert data, so if there were multiple decomposed Unicode paths in a single directory, paths after the first one were being appended to the first instead of treated as independent data.
