Form for deleted Document still works

[tennox]

Describe the current behavior

I've cloned a document and trashed the old one - and forgot to send the new form link to our team.
Next day they found that their data did not show up in the new grist after they had submitted a form... Took me a bit to realize grist is still showing the form like normal and even had written to the trashed document without complaint.

Steps to reproduce

1. create a form & share link
2. trash the document
3. Submit form

Describe the expected behavior

Form link should 404, and definitely not submit without error
