Title: Suggested updated to #1407

Only apply the is_effectively_unity check when assigning the ._scale int...ernal attribute, making it unncessary to use whenever comparing .scale to 1. This still places onus developers of the units package to remember this check whenever updating ._scale, but that's less trouble than the current case.
