Remove a redundant `PDFViewer.currentScale` call from `PDFViewerApplication.load`
Remove a redundant `PDFViewer.currentScale` call from `PDFViewerApplication.load`

Since this call occurs *before* the `PDFViewer.setDocument` call, it won't actually cause any scale change.
Furthermore, moving it should not be necessary, since the `scale` is already used as the fallback case in `PDFViewerApplication.setInitialView` (provided it's non-zero, which isn't even the case in the default viewer).

Hence this patch should cause no functional changes at all, since it simply removes a piece of unnecessary code.
