App.is_excluded_from_build() uses the wrong function entirely to query the [build.exclude] section of project.conf (App.get_project_refs() instead of App.get_value()). This has obviously never worked. It rose to prominence because commit 6db73873 introduced App.__proj_dir(), which now raises an Exception if passed garbage, which in turn surfaces as
Exception: No project path found for module "debian"
Use the correct function for that: App.get_value().
