Refactor the common code in tests_unit.yml and the integration pytest
into a single block of code.
The tests/ directory has a library sub-directory with a symlink to the
network_connections.py module. This was causing problems because the logic
in get_modules_and_utils_paths.yml really wants the real files and
directories, not the symlinks, and for some reason the bash `-f` test
is returning `true` for the symlink. Instead, ensure that we do not use
the link by using `-L` to screen it out.
Also added the collection paths to the search.
Make the path arrays have unique values.
Use the `realpath` filter to see the full actual path.
