When I saved files in my eslint-formatted projects I was wondering about
slight differences between the results of running `eslint --fix` vs. the
autoamtic formatting when I save a file in neovim.
As it turned out I ran the wrong command indeed. This changes fixes that
by simply calling the correct command on save. Note that this looks
"bigger" but it's actually a copy of the built-in `LspEslintFixAll` of
neovim.
