Ensure that PDFDocument.documentInfo doesn't fail during document load, when the entire XRef table hasn't been fetched yet (issue 8180)

Browse Source 
Similar to other `try-catch` statements in `/core` code, we must re-throw `MissingDataException` to prevent issues with missing data during document loading.
Note that I'm not sure if/how we can test this, which is why the patch doesn't include any test(s).

Fixes 8180.
