fix(aliases): Fix wikilink resolution for aliases

This is kind of hacky, but I haven't found a better way to augment
`allSlugs` - we need to have markdown parsed to get aliases from the
frontmatter, and we need to add the slugs before links get transformed
in the html plugin pass.

Fixes jackyzha0#904, don't know why you closed that
