fix(client): `deis run` no longer requires remote

TESTING: try to run a command outside of the git repository:

    $ cd ..
    $ deis run --app=foo ls

If you're running a command that contains an option flag like `ls -al`, you can specify the `--`
option beforehand:

    $ deis run --app=foo -- ls -al
