fix log_tags request object grammar
Fix for digestor to consider variants for partials -- this still needs more testing!!
Log the full path, including variant, that the digestor is trying to find
Digestor should just rely on the finder to know about the format and the variant -- trying to pass it back in makes a mess of things (oh, and doesnt work)
Update test helper to use latest Digestor API
