Replace cli::Runner with Screen (#1041)

With #1040,
`Screen` can be available in this project.

This patch replaces `cli::Runner` with `Screen`.

Note this patch also includes changes on the `tests/` directory because
tests will fail with this replacement. I'm considering refining the
tests with more readable and robust way.
