fix: cargo docs breaking in buildDepsOnly of workspaces

[dpc]

Motivation

Fix #312 by using a different name for dummy binary in every package (derived from the package name itself). This should make cargo doc happy. I tested lightly and it seems to work.

Checklist

• added tests to verify new behavior
• added an example template or updated an existing one
• updated docs/API.md (or general documentation) with changes
• updated CHANGELOG.md

Thanks for the PR! Is it possible to add a test for this to avoid future regressions?

[dpc]

Now that I have some idea how the tests work, I can try adding it later today.

BTw. I don't understand the test failed

[ipetkov]

We have some tests that cleanCargoToml outputs things as expected. Since this changes the name used for dummy binaries those tests might need to be updated as well (I'd recommend building the failing test locally to help with debugging)

[dpc]

Fixed, added test, made sure test failed before, rebased, pushed. @ipetkov

Thanks for adding the test, LGTM!
