Prevent font error when no preferred cmap table is found (workaround for issue 4800)

[Snuffleupagus]

Workaround for the error in #4800.

[yurydelendik]

Really nice finding, but I think we shall return different value at https://github.com/mozilla/pdf.js/blob/master/src/core/fonts.js#L2974 , e.g. { platformId: -1, encodingId: -1, mappings: [], hasShortCmap: false }.

Sure; I was just attempting to fix it with a one-line patch!
