IntegrityError: "pacer_case_id" is not available on some RECAP appellate attachment pages uploads

[sentry-io]

I checked some of the uploads related to this issue and found that the caseID is either blank or null in all the URLs within the upload, for example:

TransportRoom?servlet=ShowDoc&caseId=null&recapDocNum=1&recapCaseNum=20-15019&dls_id='+dls+'&caseId=

TransportRoom?servlet=ShowDocMulti&caseId=null&recapDocNum=1&recapCaseNum=20-15019&outputType=doc&d=11552967&outputForm=view&incPdfFooter=

As a result, the PQ receives a null pacer_case_id and it is also missing in the parsed data. I'm not sure if there is a different way to obtain it from the extension side, or perhaps the pacer_doc_id (available), court (available), and docket number (which is not being parsed or received in the upload) from the attachment page could be used to search for the case and docket entry.

Sentry Issue: COURTLISTENER-5T3

Thanks. Yeah, I think the better place to solve this is in the extension, so I'll migrate it there.
