PDFViewer: Fix indexing error in ErrorsView

Browse source 
I confused myself when implementing this, plus I tested using pages that
had errors in pages 1 and 2, so the index and the number of the page
(internally represented as 0-indexed) was always the same. When opening
files with errors on higher pages it became evident that there was an
issue with how I was reading the errors per page from the corresponding
ModelIndex object.
