fix(util): correctly pass --repo and -R flags to gh

- Resolve an argument indexing issue in the function that determines the
  repo flag's value.
- Make sure the -R/--repo flags and their values are passed to all gh
  commands executed by the `gh fzf util` subcommands.

Now the utils will work on repos that aren't the current directory:

    gh fzf util copy-url issue 21 --repo benelan/gh-fzf
    gh fzf util notify-run-completed 9261430053 -R benelan/gh-fzf &

gh-fzf
