Make sure the scripting manager is correctly reset when setting a null document

It should fix the error:

Please note that we should already be awaiting scripting to be destroyed via

pdf.js/web/pdf_scripting_manager.js

Lines 259 to 261 in 293506a

	get destroyPromise() {
	return this.#destroyCapability?.promise || null;
	}

which is used in

pdf.js/web/app.js

Lines 1071 to 1074 in 293506a

	promises.push(
	this.pdfScriptingManager.destroyPromise,
	this.passwordPrompt.close()
	);

and then finally

pdf.js/web/app.js

Line 1088 in 293506a

await Promise.all(promises);

I wonder if just removing the following code would possibly help here?
Given that the entire viewer is being destroyed, it seems more of less pointless (even if technically correct) to dispatch the "PageClose" and "WillClose" events when there's nothing that will actually handle them.

pdf.js/web/pdf_scripting_manager.js

Lines 162 to 168 in 293506a

	await this.#dispatchPageClose(this.#pdfViewer.currentPageNumber);
	await this.#scripting?.dispatchEventInSandbox({
	id: "doc",
	name: "WillClose",
	});
