fix: PDFMinerToDocument initializes documents with content and meta

[julian-risch]

Related Issues

• fixes PDFMinerToDocument updates Document's meta field after initializing it #8701

• related to Document ID doesn't updated upon metadata update #8692

Proposed Changes:

• Initialize the Document returned by PDFMinerToDocument with content and meta so that both are taken into account for document ID generation. Previously only the content was used for the initialization of the Document and the meta data was updated later
• Extend a test case so that the previous behavior would fail

How did you test it?

Notes for the reviewer
