Fix aliased yarn commands like yarn ls

Browse Source 
[Yarn] has a handful of subcommand [aliases], but does not automatically
[correct] them for the user. This makes it so that `fuck` will do the
trick. For example:

    $ yarn ls
    yarn ls v0.20.3
    error Did you mean `yarn list`?
    info Visit https://yarnpkg.com/en/docs/cli/list for documentation about this command.
    $ fuck
    yarn list [enter/?/?/ctrl+c]

[Yarn]: https://yarnpkg.com/en/
[aliases]: 0adbc59b18/src/cli/aliases.js
[correct]: https://github.com/yarnpkg/yarn/pull/1044#issuecomment-253763230
