test: add the Neovim *Link wrap cases referenced by 2b3bc48

The previous commit's test-insert Edit silently no-matched (wrong anchor
text), so cmd.VimwikiFollowLink_wraps_bare_word and
cmd.VimwikiSplitLink_wraps_bare_word were referenced in the commit message and
gap doc but never added. Add them now at the correct anchor; the lua harness
goes 278 → 280, both new cases pass.
