A page's `title` will be returned from Gollum/Gitaly with any +<>
characters changed to -, whereas the `path` preserves these characters.

Previously, if a title had one of these characters in it, this method
would inaccurately return true, as we would be comparing `my+page` with
`my page` (after unhyphenization).
