Access the Catalog data correctly in the "GetPageIndex" handler in src/core/worker.js

Browse Source 
Even though the code obviously works as-is, given that we have unit-tests for it, it still feels incorrect to just *assume* that the `Catalog`-instance has all of its properties immediately available. Especially when (almost) all of the other handlers, in `src/core/worker.js`, protect their data accesses with appropriate `pdfManager.ensure` calls.
