Reviewed by Simon Fraser.

PDFPlugin::getResourceBytesAtPosition is triggering a load to a PDF resource previously done by a document loader.
This new load is using range requests, it should thus not be considered as a main resource request.
Given the original resource request is coming from a document loader, we need to explicitly set back the requester to unspecified.
