It turns out that the target extension here in `ext` has a dot prepended.
Under manual testing, this seems to fix the issue where a wiki with
`markdown_link_ext` set and using `.md` (for example) in links will wind up
taking people to pages with a repeated extension, like `foo.md.md`.
I feel like the repeated use of:
vimwiki#vars#get_wikilocal('ext', link_infos.index)
here should probably be replaced with a named variable like `target_ext`,
but I wanted to touch the minimum lines of code possible for this fix.
