fix(fish): Don't handle level 3 nested subcommand

Browse source 
Nested subcommand more than 3 levels is not practical in public.
Take rustup for example, `rustup toolchain install <version>`,
there is only 3 levels of nested subcommands. But there is also
the case of `rustup help toolchain install`, or `rustup toolchain help install`.
