Pre-installed Nix removal instructions miss user's fish

[suntropez]

The installer makes a suggestion of removing pre-existing Nix things.

https://github.com/NixOS/nix/blob/master/scripts/install-multi-user.sh#L139

In my case, I had $HOME/.config/fish/conf.d/nix.fish from the single user install. The new installation added /etc/fish/conf.d/nix.fish. Since Fish let's the former override the latter, /etc/fish/conf.d/nix.fish was not being sourced. Maybe, and this is just a suggestion, the installer could remind or suggest removal of shell specific files. It took me a bit of investigation to realize what was going on so this might happen to more people, hence the suggestion here.

To be clear, although $HOME/.config/fish/conf.d/nix.fish existed, the content was meant for the single user install which had been removed.
