Paul Dardeau 331382e192 Add unit tests to cover print_item_locations
Add unit tests to cover all code paths in print_item_locations
function in cli/info.py.

Update comment to match what's tested for invalid/missing policy.

Update tests to verify output of print_item_locations

Corrected PEP8 compliance violations.
