[Common UI] Fill in new specs

Complete test coverage for new scripts added to bundle
platform/commonUI/general in suport of autoflow
tabular views, WTD-614. Specifically, these provide a
directive to watch element sizes, and a controller to
help as an intermediary between getter-setter style
ngModels, and plain assignable ones.
