Fix order of dictionary type entry for /CIDToGIDMap for CID fonts

The DictionaryConverter module uses the first entry in the type array as the type class for the conversion. Since the converter is invoked for /CIDToGIDMap due to 'Stream' being in the type array, it use 'Symbol' as type class which is invalid.
