Describe the bug

fn configure_pcx_from_compile_output relies on ProjectCompileOutput.sources() to figure out the sources that solar should ingest. However, when the source code doesn't change between compiler runs, compilation is skipped and sources is empty.

This behavior wasn't caught by unit tests, and causes solar analysis capabilities to only be available on the first test run.
