[src/core/worker.js] Remove a useless Promise handler from the pdfManagerReady function

Browse Source 
Looking carefully at this code, you'll notice that the `loadDocument` function has no less than *three* Promise handling functions. This obviously makes no sense, since a Promise can only have one resolve and one reject handler.

Hence the final `onFailure`-case is unreachable, which only serves to add confusion when reading the code. Note that this code has been re-factored more than once over the years, but it seems as if this may even have been incorrect already in PR 3310 (and no-one have noticed for seven years :-).
