By doing a single `cargo build` ahead of time, we are creating all
necessary binaries at once. This allows our cache to work for tests
as well as the binaries.
There is also no need to use release binaries for the smoke test.
Building debug binaries is a lot faster and serves the same purpose:
Checking whether the application actually starts up.
