Subject: [PATCH] neovim.tests: neovim-plugin-config

make test TEST=neovim-plugin-config

- would previously use `-u` which we precisely want to avoid relying on
because of side-effects.
Likewise,  `-es` skips some initialization phase (see `:h startup`).
- Instead of several stdout redirections, write to a file directly.
- also logs more via -V3$out/log.txt to help debug
