Show PDF.js viewer when PDF.js FlipFlop is true

This is a workaround to unblock Mobius ingests. If the feature flipper to display PDF.js is true, we will display that viewer regardless of the property values of :show_pdf_viewer and :show_pdf_download_button.

We will revisit valkyrizing this feature fully in the future, when we start the iiif x valkyrie epic.
