Fixes a stupid oversight on my part, since /Filter may (obviously) contain an Array, which resulted in unnecessary console warning spam in perfectly valid PDF files.
Note that it still makes sense to check that /Filter is actually a Name, before attempting to access its
name
property, but the warning should definitely be removed.Much smaller diff with https://github.com/mozilla/pdf.js/pull/9954/files?w=1
