fish: Use nvr instead of floaterm

nvr seems to allow opening a file at specified line just like with
regular nvim which seems to not work for floaterm. So when in neovim
terminal vgrep -s opens the file at correct line while in floaterm it
just opens the file and puts us at the first line. Basically something
like nvim +99 file.c does not work for floaterm.
