Fixes some assets not being saved with SingleFile snapshots

Browse source 
Part of zotero/zotero-connectors#394

When saving an item (e.g. on arxiv) with a site translator, the
translator may add a custom snapshot attachment URL which does not match
the translation URL (the URL in the browser where translation was
initiated) in which case Zotero handles snapshot saving. Zotero loads
the page in a background browser. By default images are not loaded in
this browser. SingleFile due to CORS restrictions has to refetch all
resources that are not from the same domain or subdomain, but uses
pre-loaded resources (images) from the same domain. Before this change
any images that were from the same domain as the saved website were not
saved in the snapshot. This commit fixes that.
