Resolution for base URIs with empty path

[drobilla]

Hmm... turns out this might not be so trivial. Serd's URI resolution is written to be in-place, so no allocation of new nodes needs to be done when streaming, but this special case messes that up, since a slash needs to come from somewhere that doesn't exist.

Maybe I can instead tinker with the serialisation stuff to detect this case and emit an extra slash. This wouldn't make a slash magically appear for people manually using serd_uri_resolve and friends, but it should be possible to handle it everywhere a resolved URI is actually serialized (either with the writer or to a new node). My only concern is that this could mess up weird URI schemes, but you can't have an authority and a path without a delimiter, so I think this is fine as long as an authority is actually present...

3267bb3 should do it.
