nvim: Fix ltex disabled autostart

Fixes #1ef7570.

We implement our own autostart-aware lsp register function. Any lsp
which has the option {autostart=false} set at their config root will be
not automatically enabled and can instead be enabled on demand.

     This alias only works when the dotfiles are cloned into `~/.dotfiles`, mirroring my setup.
     This is due to a hard-coded cd into this directory.

 Both automatic installation paths are presumably somewhat brittle. In any case, I would suggest to manually look through the files for things you want instead of copying and activating everything.
 Dotfiles are too personal to be standardized like that.
