Tweak the useWorkerFetch default value checks (PR 15879 follow-up)

Browse Source 
Currently we accidentally accept `cMapUrl` and `standardFontDataUrl` parameters that are empty strings or `null`, since e.g. `new URL(null, document.baseURI)` doesn't throw, when validating the `useWorkerFetch` parameter via the `isValidFetchUrl` helper function.
Please note that we are currently failing gracefully in this case, as intended, however the warning-messages printed in the console are perhaps less helpful without this patch.
