Subject: [PATCH] spack config update (bugfix): packages.yaml with empty
attributes (#18057)
Before this PR, packages.yaml files that contained an
empty "paths" or "modules" attribute were not updated
correctly, since the update function was not reporting
them as changed after the update.
This PR fixes that issue and adds a unit test to
avoid regression.
