When transforming to views, always use master branch data (#346)

Should close #219
actions/checkout#439 (comment) encourages setting the ref explicitly to always pull the latest data from the ref.
When performing the transformation to views, we always want to use master data, so it is safer to set the ref unambiguously, instead of using the inherited reference (which may come from a different branch/commit).
