Let the PdfManager.requestLoadedStream method return the stream

Browse Source 
*This is very old code, and it could thus do with some simplification.*

Note how in the `src/core/worker.js` file we're combining both the `PdfManager.requestLoadedStream` and `PdfManager.onLoadedStream` methods in order to access the stream-data. This seems unnecessary, and it's simple enough to always let the `PdfManager.requestLoadedStream` method return the stream-data as well.
