Buran 1.9 crashing on relative redirects without leading slash

[acidus99]

Noticed Buran 1.9 crashes on these links:

gemini://the-brannons.com/about gemini://the-brannons.com/posts

Both return a 31 redirect without a leading /.

e.g.: gemini://the-brannons.com/about return 31 about/

I forgot to include the protocol scheme in the redirect resolver. Fixed.
