Add an extra specbundle_update

I wanted to make sure that `bundle update` no longer updates the whole
bundle after we change the behavior, since I thought maybe I needed an
early return after the help text was printed. After writing the test I
realized that the `help` command is exec'ing, so no, we don't need the
early return. But I guess the test doesn't do any harm.
