Fix handling of links that only consist of fragment

If a link only consists of a fragment (#something), we must not resolve
that relative to the "base" url, which is basically the "path" of the
current document. It should be resolved wrt the document URL (including
the file name), which we currently don't have available in the container
implementation. Just return the fragment unchanged and let the link
handler take care of that, like it was before
