Stop warning for non-Name /Filter entries in the PDFImage constructor (PR 9897 follow-up)

Browse Source 
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.
