Missing DocumentID when analyzing manually

[mightyjens]

First of all, thank you very much for this great project and your work! Awesome!
I'm not that much into Javascript programming, but I hope my debugging helps a bit.

Describe the bug
When manually analyzing a document, the document id is not passed to the analyzeDocument() method.
This results in an error when fetching the thumbnail from paperless when there's no cached thumbnail present.

First of all thanks for you kind words :)

I will look later again into your issue, have bit of a struggle fixing an error with v2.1.1 right now.
