neovim: cursorless.nvim won’t work if user has other node remote plugins

[saidelike]

This is because atm only one place can register node functions (https://github.com/neovim/node-client/issues/356). cursorless.nvim does it manually on its own, which means neither another plugin can do it in their own plugin nor can it be done in the default rplugins.vim (with “:UpdateRemotePlugins”) or it will conflict with cursorless.nvim. If that happens, the first plugin registering node functions will win and the other will fail. This will be solved by https://github.com/cursorless-dev/cursorless/issues/2397
