Jonas Jenwald 24fc4f83ca Small clean-up of the PDFDocumentProxy.destroy method and related code
Note how `PDFDocumentProxy.destroy` is a nothing more than an alias for `PDFDocumentLoadingTask.destroy`. While removing the latter method would be a breaking API change, there's still room for at least some clean-up here.

The main changes in this patch are:
 - Stop providing a `PDFDocumentLoadingTask` instance *separately* when creating a `PDFDocumentProxy`, since the loadingTask is already available through the `WorkerTransport` instance.
 - Stop tracking the `PDFDocumentProxy` instance on the `WorkerTransport`, since that property is completely unused.
 - Simplify the 'Multiple `getDocument` instances' unit-tests by only destroying *once*, rather than twice, for each document.
