Prevent errors, in PDFOutlineViewer._getPageNumberToDestHash, for invalid destRef values (PR 12777 follow-up)

Browse source 
Currently `destRef === null`, which will only happen in documents with corrupt destinations, will (unsurprisingly) throw when trying to lookup the pageNumber. To avoid this, we can simply use the same format as in 1a2cdaffc5/web/pdf_link_service.js (L128)
