Test the whole workspace at once in ci-tests.sh

Running `cargo test -p crate` for each crate in the workspace
results in re-building the `lightning` crate for each workspace
crate, which can be quite slow. This adds nontrivial time to our
total CI runs.

Here, instead, we just run `cargo test` and let it build the whole
workspace crate list in one go. This does result in combined
features which may leave some issues with `cargo test -p crate`
undetected, but there's not a ton of harm to that.
