Fix support for Gemini links with optional label

Previously, if a Gemini link did not have a label, then sbs would skip
converting it to a Markdown-style link. For example:

=> /this/is/a/link.gmi

would not get converted whereas:

=> /this/is/a/link.gmi Link

would get converted. Since the label is optional according to the
gemtext specification, we need to support these situations.
